Restoration Roadmaps

The ability to reveal the hidden layers of hydrology can take many forms. Public art is a great mechanism for telling stories in ways that engage and reveal that which is often missing from our day to day experiences. These artworks also highlight key contributions of communities that are often marginalized in the official histories we are taught. Artists Shu-Ju Wang and Lynn Yarne developed a vibrant example of this at the new Lincoln High School in Portland with a large exterior mural called Restoration Roadmaps which locates the hidden hydrology story within the context of the urban high school. The summary of the project, from the artist’s website for Restoration Roadmaps provides some of processes and the outcomes:

“The process enabled us to come to a final design that is a combination of several forms of maps to describe the neighborhood–from historical to a hoped for future, from topographical to ecological, from google map to the old fashioned foldout map. Student and community responses are recorded as part of the topographical contours and inset panels.”

The images are rich with detail, focusing on the high school site and the contemporary grid, juxtaposed with the Tanner Creek historical route with other water bodies that have been erased. The creek gulches were the locations of highly productive garden areas farmed by Chinese immigrants and also provided historical areas of Native American occupation. The mural includes smaller square panels with community work done by other artists and students, and the perimeter of the mural provides detailed assemblages of 40 species of flora and fauna Indigenous to the area.

It was fun to see the process evolve and the final product ‘in the wild’ below. Let me know if you’re local and have seen the mural, or if there are other murals in your community celebrating hidden hydrology. Would love to hear from you.

HISTORICAL BACKGROUND

The lead-up to the public process included some great information compiled by a series of experts on the history, ecology, and culture around the Tanner Creek area and the Chinatown farmers. These included lectures by Dr. Tracy Prince on Native American Traders and Chinese Vegetable Gardens in the Hollows of Old Portland, and Native Americans of Old Portland, and a co-presentation Notable Women of Portland, by Prince and her daughter Zadie Schaffer, who is also a Lincoln alum. Dr. Marie Rose Wong, author of Sweet Cakes, Long Journey: The Chinatowns of Portland Oregon gave a talk on Tanner Creek and Portland’s Chinatown. Eric Butler, a restoration expert, included information on the Ecological History of Tanner Creek.

Beyond helping with some mapping for the mural, my other contribution was this short video, Tanner Creek Hidden Hydrology, walking through the history of the area in the context of the historical water. I’ve included the video below:

Subterranean Cisterns

Jason Kingarchaeology, art, city, design, explorations, history, infrastructure, maps, places, san franciscoLeave a Comment

There are a number of stories that occasionally receive comments and inquiries on posts from back in the day. This past few weeks, readers reached out related to the 2017 post “San Francisco’s Hidden Water Tanks” (Hidden Hydrology, 12.15.17), inquiring about a really cool hidden feature of the urban realm.

The post drew on a great article published at the time by CityLab/Bloomberg, “The Sublime Cisterns of San Francisco” (05.01.17), which explains the presence of brick circles located at numerous intersections around the downtown core of the city, such as the image below.

Brick circles denote the location of old cisterns (via Bloomberg)

These reference the locations of underground cisterns, dating back to the 1850s, which were state-of-the-art in fire protection in the 19th and early 20th centuries. These cisterns were distributed around the downtown area and filled with water, which supplemented fire brigades and enabled them to pump water for fire-fighting prior to implementing pressurized water systems and fire hydrants. As noted in the Bloomberg article related to the need for new modern fire protection in cities:

“One of the ways officials responded to these blazes was to build cisterns. These subterranean vitrines were designed as a last-resort source of agua for firefighting. San Francisco’s 19th-century cistern system was reinforced with more, larger cisterns after the Earthquake of 1906, whose subsequent firestorm killed roughly 3,000 and left much of the city’s land looking like a blasted moon. To date there are 170 to 200 of the tanks stashed around town.”

Many of the remaining cisterns are intact below ground, revealing subterranean spaces unknown to those walking and driving above. Many are empty, but some are still used as emergency water sources today.

John Oram, aka the prolific Bay Area blogger Burrito Justice, dug deep into the cisterns as far back as 2011. Around 2016, when the original Bloomberg article was published, he created an interactive map (unfortunately no longer available) of their subterranean locations. The map represented the intersections where the cisterns were located, scaled by the capacity of the cistern below.

Another resource for these cisterns, which Oram used in his mapping project, was a 2014 project by Scott Kildall. As part of an art project called “Water Works,” Kildall focused on “…a 3D data visualization and mapping of the water infrastructure of San Francisco.” He also created an interactive map (now also unavailable) of the cisterns, and the project generated some interesting maps and art around the locations of key infrastructure, including cisterns, as seen below.

For those interested in a deeper dive from these past sources, I recommend “What’s Underneath Those Brick Circles?” (Burrito Justice, 03.08.13), and “Cistern Mapping Project Reportback.” (Scott Kildall, 01.07.16). Although a seemingly hot topic in the mid-2010s, I only found a few scant more recent references to these cisterns. A good one worth listening to is part of a self-guided tour of these cisterns as part of the Exploratorium installation Buried History – Water Underground along with a link to a downloadable, printable map here.

I would appreciate any input from anyone in the Bay Area with up-to-date information or ongoing projects related to the cisterns.

Water Kinship

Jason Kingart, creeks, cultural, ecology, explorations, habitat, landscape, language, literature, oregon, places, rivers, sensesLeave a Comment

The article “Reaching the Light of Day” (Orion, May 23, 2024) is compelling if you’re interested in hidden hydrology. Author Corinne Segal recounts some of the larger themes and projects around “ghost streams,” including work in New York, Baltimore, Auckland, Istanbul, and a handful of other locations. Beyond some of the projects they note, the article poses a larger question regarding our ancient ‘kinship’ with water. This struck me as essential to the conversations around hidden hydrology, so took this as an opportunity to explore further. Various nuances and definitions of kinship span from biological to sociological. For a reference point, I grabbed this quick definition:

kin·ship /ˈkinˌSHip/, noun. blood relationship; a sharing of characteristics or origins.

One could make a case for both parts of this definition. While we’re not technically related, there is a physical biochemical connection between our bodies and water, as our lives ultimately depend on water for our existence. Thus ‘blood relationship’ takes a literal dimension: healthful when we talk of life-sustaining properties; harmful when we talk about, for instance, toxicity due to water pollution. The negatives are often of our own doing, caused by abuse or neglect of our ‘kin’ impacting our bodies in negative ways with disease. It is a kinship of reciprocity, reflecting a link between our treatment of our ‘kin’ and how it is tied physically to our survival.

The second definition here is most compelling, diving into our deeper emotional relationship with water. The ‘sharing of characteristics or origins’ resonates powerfully with our relationship with water. This summer I read the 2023 posthumously published dialogue with Barry Lopez and writer Julia Martin titled Syntax of the River: The Pattern Which Connects. Much of the discussion focused on how Lopez engaged that kinship early in life through language, as a way to know, only later in life, expanding the relationship through a deeper dive into “syntax” to develop understanding and attain wisdom.

An excerpt from his elaborates on this idea:

“I think when you’re young you want to learn the names of everything. This is a beaver, this is spring Chinook, this is a rainbow trout, this is osprey, elk over there. But it’s the syntax that you really are after. Anybody can develop the vocabulary. It’s the relationships that are important. And it’s the discerning of this three-dimensional set of relationships that awakens you to how complex this is at any one moment.”

The only way to develop these three-dimensional relationships is through consistent contact, which requires occupation of and awareness of place. As he visits and revisits his local McKenzie River, he partakes in constant unfolding. He notes some of these observations: “The water has a slightly different color during the four seasons, depending on how much snow and glacial melt is in it. And the parts of the river that are not visible in the summer are visible in the winter, because of the loss of leaves of deciduous trees.”

This connection with water, as Lopez describes it, requires spending time physically interacting with these environments, and conducting actual visits with our ‘kin’ to deepen ties. The wrinkle here is how we adapt this approach for the ‘lost’ or ‘forgotten’, those hidden streams and buried waterways that no longer have a discernable physical presence. The relationship is no longer about observation in the present but about memory. This perhaps is similar to thinking about our lost kin, to think of lost streams in terms of death. In this way. This could be a way to reframe the relationship as grief and loss, allowing us to draw from the deep well of resources to rethink how we remember and celebrate those lost relationships.

I’m reminded of one of the origin stories of Hidden Hydrology, with author David James Duncan recounting a tale in his fabulous book “My Story As Told By Water”, of the death of one of his favorite fishing spots in his stomping grounds east of Portland:

“At six-thirty or so on a rainy April morning, I crept up to a favorite hole, threaded a worm on a hook, prepared to cast – then noticed something impossible: there was no water in the creek. …I began hiking, stunned, downstream. The aquatic insects were gone, barbershop crawdads gone, catfish, carp, perch, crappie, bass, countless sacrificial cutthroats, not just dying, but completely vanished. Feeling sick, I headed the opposite way, hiked the emptied creekbed all the way to the source, and there found the eminently rational cause of the countless killings. Development needs roads and drainfields. Roads and drainfields need gravel. Up in the gravel pits at the Glisan Street headwaters, the creek’s entire flow had been diverted for months in order to fill two gigantic new settling ponds. My favorite teacher was dead.”

It is sometimes challenging to think of hidden hydrology through the lens of grief, but you can feel Duncan’s pain at the loss of this urban creek. It’s one cut in the death of a thousand cuts that makes up the global tragedy — the devastation wrought throughout the world on waterbodies in the name of progress. However, the impact is muted for several reasons. First, we, unlike Duncan, are often not around when most of these creeks and streams existed in the first place, so we don’t comprehend what we lost. Second, there are remnants and surviving resources that we can still connect within our cities, so the erasure is not complete enough to equal extinction. Finally, these places fade from memory, and, out of sight, out of mind, we forget as we trod over their buried pipes and filled depression blissfully unaware.

When we lack a strong presence of these historical remnants, we tend to feel greater disconnection, the subtle traces not sufficient for us to feel a connection. This drives our need to reveal and reconnect using a variety of methods: artistic, metaphorical, and ecological. This is hidden hydrology as a practice: the reason for us to study old maps, trace the lines of old creeks, and attempt to restore kinship.

Baltimore Ghost Rivers – via Orion Magazine

Hidden hydrological features, unlike humans, can physically be restored and brought back to life in a sense. Beyond just memory, we have the potential for rebirth, through our creative endeavors: historical ecology mapping, painting the routes of streams on roadways, ecological restoration, and daylighting. “Back from the dead” seems a morbid way to think of the processes of restoration, but it gives us the ability to reconnect and restore.

Several other themes can intersect and expand this idea. I recently re-read a portion of Braiding Sweetgrass, where Robin Wall Kimmerer talks of the Grammar of Animacy. I am struck by the similar themes of kinship, as she discusses how we relate to and reference these ecological systems. An excerpt from an Orion article from 2017, “Robin Wall Kimmerer on the Language of Animacy” hints at this idea:

If it’s just stuff, we can treat it any way that that we want. But if it’s family, if it’s beings, if they’re other persons we have ecological compassion for them… Speaking with the grammar of animacy brings us all into this circle of moral consideration. Whereas when we say “it,” we set those beings, those “things,” as they say, outside of our circle of moral responsibility.”

We connect our morality to things we understand. Another theme that this also evokes is the writings of Robert Macfarlane, particularly when he speaks of language and how words connect us to the natural world, another form of ‘kinship’. I wrote eons ago about this lost language of nature, including Macfarlane and Anne Whiston Spirn, both of who also have written about lost rivers. Along with Lopez and Kimmerer, these authors prod us to rethink our ability to connect with our kin, hidden or visible, degraded or pristine.

I’m curious to hear your thoughts on how we can develop and expand these relationships, our ‘kinship’, specifically with places no longer visible and viable. Are there good examples you know of where lost relationships have been reestablished? Do you feel a kinship or even see this as a goal, with other species or with the wider landscape?

Lost Channels of the Nile

Jason Kingarchaeology, canals, cultural, explorations, history, infrastructure, maps, places, riversLeave a Comment

Throughout history, there are numerous theories about building the Great Pyramids of Giza along the Nile River in Egypt. One of the key questions has been the logistics of moving the massive stones, each weighing over two tons. 2.3 million of these blocks of limestone and granite were used to construct the structures, without the aid of modern machinery. Theories for how this was accomplished vary and include methods of transport over land via sleds and rollers, and construction on-site using ramps, and pulleys. Some even attribute these other-worldly feats more broadly to the work of aliens.

Water and the Nile have always been tied to these theories, with the idea that the blocks were floated on the river from distant quarries for use on-site for the Pyramid construction. The structures sit at a slightly higher elevation from the floodplain, some distance from the main channels of the Nile, thus there have been questions on how the stones were transported this last mile from the river to the site itself. The research questions used the tools of hidden hydrology to develop theories on lost channels instrumental to the construction. Two such theories are discussed below.

Khufu Branch

Research on a proposed lost side branch of the Nile being used for aiding in construction was discussed in 2022. I read about it in the article “A Long-Lost Branch of the Nile Helped in Building Egypt’s Pyramids.” (NY Times, 08.30.22), which discusses research results from the paper: “Nile waterscapes facilitated the construction of the Giza pyramids during the 3rd millennium BCE” (PNAS, 08.29.22). The article posits the use of a now-defunct Khufu branch of the Nile River that bent towards the assemblage in Giza to aid in transporting the giant slabs of stone to the building zone.

The researcher’s process involved looking at soil cores: “Seeking evidence of an ancient water route, the researchers drilled down into the desert near the Giza harbor site and along the Khufu Branch’s hypothesized route., where they collected five sediment cores.” Analysis of the samples included paleobotany to look at plant fragments and pollen, and matching these species with the presence or absence of water-adapted or dry plantings to determine if the areas were part of a historical water body. The results showed periods of inundation that matched the construction of the pyramids.

This wet period allowed standing water to persist, and the proximity of the Khufu branch provided the ability to extend the reach of the Nile, allowing the construction of smaller canals close to the area of the Giza plateau. The branch is theorized to have dried up around 600 B.C. and the channel moved further away from the site of the Great Pyramids.

Ahramat Branch

Several current articles (Cosmos, BBC) have reignited this dialog around these theories of the use of waterways for transporting building stones. They all refer to research from a May 2024 paper entitled, “The Egyptian pyramid chain was built along the now abandoned Ahramat Nile Branch.” (Nature Communications Earth & Environment, 05.16.24). The research team offers new theories about investigating the hidden hydrology to unlock these ancient mysteries. As noted in the article the team makes a similar assertion to the previous work on the Khufu Branch, however, they consider the hydrology differently as a parallel side channel they refer to as the Ahramat Branch. From their abstract:

“Many of the pyramids, dating to the Old and Middle Kingdoms, have causeways that lead to the branch and terminate with Valley Temples which may have acted as river harbors along it in the past. We suggest that The Ahramat Branch played a role in the monuments’ construction and that it was simultaneously active and used as a transportation waterway for workmen and building materials to the pyramids’ sites.”

The map below shows the route of the Ahrama Branch, which was situated on the western edge of the floodplain closer to the location of the Pyramids. In this case, the proximity extended the length of the Pyramid complex, including those to the south near Memphis. The study offers the opportunity for new information, protection of cultural sites, and outline areas to protect from urban development.

The research team discusses the project directly in an article: “We mapped a lost branch of the Nile River – which may be the key to a longstanding mystery of the pyramids.” (The Conversation, 05.16.24). They discuss the methodology of using satellite images, digital elevation models, historical maps, and other sources to identify the traces of the waterway. As they note, there are ‘causeways’ that look to connect at the points of the major construction areas, which were used as “docks” for loading and unloading materials and for workers moving up and down the river.

The idea of understanding the historical hydrological elements of the river provides a unique approach, noted by the team:

“This research shows that a multidisciplinary approach to river science is needed to gain a better understanding of dynamic river landscapes. If we want to understand and protect the rivers we have today – and the environmentally and culturally significant sites to which they are inextricably tied – we need a greater appreciation of the interconnected factors that affect rivers and how they can be managed.”

Similar to the Khufu branch, there are theories about what eventually happened to the Ahramat Branch. These include the gradual migration of the channel, tectonic shifts that changed the floodplain drainage, or accumulation of sand filling up the channel, concurrent with other desertification processes at work. The climatic shifts could also have led to more arid conditions and dissipation of the side channel due to lower flows.

Check out the articles and papers for much more detail. I appreciate these larger-scale investigations of hidden hydrology, especially when they intersect with the complexity of ancient constructions, providing hints of how water was instrumental in these monumental endeavors. It shifts the attention away from the typical urban focus of hidden hydrology, which concentrates on the burial and piping of streams in cities, positioning the investigations of hydrology through bigger contexts and longer timescales. And, it’s a pretty cool way to solve a mystery.

Ghost Rivers of Baltimore

Jason Kingart, baltimore, case study, city, creeks, cultural, design, explorations, maps, places, streamsLeave a Comment

One of the cooler examples of hidden hydrology art in the past year is “Ghost Rivers”, the brainchild of designer and artist Bruce Willen of studio Public Mechanics.

Envisioned as a “…public art project & walking tour, rediscovering hidden streams and histories that run beneath our feet.” Willen uses traffic striping and signage to highlight multiple sites around the city, particularly Sumwalt Run, a buried creek that “now flows entirely through underground culverts beneath the Remington and Charles Village neighborhoods.”

The site includes some great background, including the history of the streams and their burial, along with some great illustrations of the path as it winds through

Stream burial (Baltimore DPW Archives, Ronald Parks – Ghost Rivers)

The installation itself is simple, using durable thermoplastic traffic striping in a wavy pattern that allows the line to engage with people in multiple ways and follow curbs and walks – so it is interrupting the linear flow patterns of walkers, cyclists, and driver throughout the city. This allows the eye and the curiosity to wander along these paths and connect the dots.

Images of the meandering blue path in the public realm (Ghost Rivers)

Self-guided walking tours are available and will expand as more sites are included, along with a Google map to track the route and key points. The signs are also simple, but bright and noticeable for those passersby, allowing for a bit of interactivity as they line up with the views of the meanders, and provide some background information and QR codes to scan for more engagement.

The summary statement explains the idea of connecting us with these hidden creeks.

“Below the streets of Baltimore flow dozens of lost streams. These ghost rivers still cascade from their sources, the many natural springs around the city. As the street grid sprawled outward from the harbor, these verdant waterways were buried in concrete tunnels. They now run deep beneath our rowhomes, channeled into the city’s storm sewers, hidden and mostly forgotten. You can sometimes hear their rushing waters echoing up from storm drains.”

The site also includes awesome resources for more information, history, daylighting resources, and other artistic interventions worthy of a follow-up, including a few I’ve posted about in the past and a few new ones. This is a model that is highly replicable in almost any city, using materials that are simple and evocative in unique ways to highlight those subterranean stories and make us reconsider our relationships with the hidden hydrology.

The idea is one of the most cohesive and elegant takes on the idea of revealing creeks using blue lines tracking the historical routing of the waterways. It draws upon precedents, mentioned by applying traffic coating, markers, or paint to mark the route of creeks, most similarly artist Sean Derry’s work in Indianapolis ‘Charting Pogue’s Run” and Henk Hostra’s “The Blue Road” in Drachten, The Netherlands, the proposed “Ghost Arroyos” in San Francisco. Another art-based example from Baltimore is the “Green Alley” street painting, and more loose, ephemeral versions in the St. George Rainway in Vancouver, B.C., in São Paulo, Brazil as part of the Rios a Ruas project, Stacy Levy’s Stream Sketches in New York City.

There are lots of examples of this type of project, and it is interesting to see the different ways a simple blue line can be used to engage in revealing historical layers. So let me know if you have other favorites you’ve seen.

Tokyo Drift

Jason Kingart, case study, creeks, cultural, explorations, history, language, maps, places, streamsLeave a Comment

The article “Tracing Tokyo’s Hidden Rivers” (The Japan Times, March 2024) was a fascinating dive into hidden hydrology mapping and urban exploration through the lens of Japanese culture and added a new term to my lexicon. The concept of ankyo, 暗渠. which at a basic level translates in English to something akin to “culvert”, “conduit” or “subterranean drain”. These features have been removed from the city’s original landscape, yet still reveal themselves in numerous ways. This is the starting point for Hideo Takayama and Nama Yoshimura, who together started “Ankyo Maniacs”, a group focused on exploring these urban remnants of buried and hidden streams in the City of Tokyo.

Tours of the ankyo reveal waterways flowing under manholes (The Japan Times)

The explorers rely on what they call “ankyo signs”, which include a wide range of markers that help clue us into the hidden hydrology, including place names, objects, and drains (such as shown above) which allow the visual and auditory connections to flowing water. There are also urban remnants such as barriers and old bridges that were previously in place to protect from open waterways but were never removed, or prevent access to areas that have been covered over. More obvious are places focusing on water, including baths, pools, and fishing ponds. The Ankyo Maniacs and others have refocused attention on these liminal spaces, as mentioned in the article:

“While they may be out of our sight, Takayama says water still flows through many ankyo, while others have become part of local drainage systems. “It’s as if they’re telling us, ‘We’re still here,’” he says. “By getting to know them, we can appreciate the past dignity of these rivers.”

The basis for the exploration relies on several maps and the history of Tokyo spans many years. The Tokyo Ankyo Sanpo (Tokyo Ankyo Stroll) map, edited by So Honda, provides the go-to for locals exploring the city with ankyo and other features mapped in detail. Another more modern resource is the Tokyo Jisou, or Time Layer Maps, available as an iPhone and iPad app, which is a map viewer that shows maps of the city at different periods, spanning the Meiji to Heisei Eras from the 1800s to present time.

Images from the Tokyo Jisou Maps – by the Japan Map Center (App Store)

Beyond the specifics of mapping and exploration, the language of hidden hydrology is also fascinating, the Japanese term “ankyo” providing a case study of the hidden poetry of the terms. At a basic level, ankyo describes these places in practical terms, as drains and culverts that work to convey water underground. When you look at the underlying meaning of the characters, it hints at ideas like ‘darkness, shade, disappearance’ which allude to the more mysterious nature of the network of underground features that compel us to explore. The Tokyo Ankyo Sanpo map mentioned previously also includes the opposite features “kaikyo” 海峡, which are the still-visible open channels, evoking lighter ideas like ‘cheerful, pleasant, and agreeable’.

An example of one of the tours is found on the Experience Suginami Tokyo site, providing self-guided instructions in the area of Ogikubo Station following the route of the former Momozonogawa River and portions of the Zenpukujigawa River, including “ankyo signs” such as alleys and paths that act as covers to the buried streams, curving walkways mimicking the previous channels, and other hints at the hidden histories underneath.

Ankyo (Culvert) Tour map near Ogikubo station (Experience Suginami Tokyo)

The heart of the process isn’t just about the learning or processing of information, but about the experience. The prompt by the explorers: “Don’t Think. Walk and Feel!” is imbued with ideas about slow time, and the benefits of connecting to places more deliberately. It also connects to larger ideas about experiencing places, observing and connecting to the signs and features of the urban landscape, expressed in the Japanese concept of ‘wabi-sabi’, allowing appreciation of nature, along the way.

The language barrier does limit my full understanding of the content, (including what seems like some great publications) so if any Japanese speakers have more to add, I would love to hear it. For some bonus content, this short video with Takayama and Yoshimura in Tokyo outlines their work exploring the ankyo.

The idea of revealing the locations of hidden places is compelling for all who study hidden hydrology in its many forms. As summed up in the video: “Ankyo hunters say they enjoy the idea that at any moment you could be standing over a piece of forgotten Tokyo.”

Lost Waterways of Dublin

Jason Kingcity, creeks, Dublin, explorations, history, maps, places, precedents, rivers, streams5 Comments

Dublin is another city with a rich history of lost waterways, so as a quick follow-up to the previous post about Belfast, let’s keep the focus on Ireland for a bit longer. The best source for this is a great article by Arron Henderson, “The Poddle and Dublin’s Hidden Rivers“, which mentions that there were over 60 watercourses flowing at one time. While a few remain such as the Liffey, Dodder, Santry, and Tolka – most are either completely gone or mostly underground. Henderson focuses on the Poddle, “…which runs underground for the majority of its course.”

The Poddle flows under Bridge and over a Weir at Mount Argus (via Dublin)

He points of the importance of these hidden streams, and how learning about them can connect with the history of places, sometimes in the margins, and often long erased from memory.

“It’s clear the Poddle played a crucial role in shaping Dublin’s history over so many hundreds of years. Providing our drinking water, powering mills, providing water for brewing, tanning, distilling and market gardens. This explains why, once they learn about it, people tend to treat this modest little river with interest and affection. An affection which is, after all, no more than it deserves.”

The River Tymon/Poddle near its source, as it flows out from Tymon Park – (via Dublin)

As mentioned in the article, there are many other hidden rivers, including the Swan, and place names emerge, with stories about the shopping center named after Rathmines, one of the tributaries of the Swan. Also some etymology, like the suffix “-iken” which means small, and one of Dublin’s rivers named in homage of another larger river named the Nanny, becoming it’s smaller namesake, the Naniken River.

For some exploration, there’s a map that I found, but can’t figure out the author, showing “dublin river past present and culverted“. A snapshot of the map is here, but it’s explorable via the Google map. Many of the waterways are untitled (and perhaps unnamed), but some are identified. Let me know if anyone knows the creator of this one.

These buried streams emerge during construction such as this view of the Swan River on Mount Pleasant Avenue and the old brickwork vaulting.

Similarly, this leads to opportunities for students to explore and learn about these hidden local waterways, as shown in this story from Dublin People, “Students explore hidden Northside waterways” and The National Neighborhood efforts to connect school kids to this hidden hydrological history. ” Led by artist Claire Halpin, the students are investigating the hidden rivers of Finglas and the Tolka river valley, and with the help of the National Museum of Ireland Collins’ Barracks Education team, are getting a chance to see first hand how their ancestors got around on the waters of north-west Dublin. “

“Already they have been learning about the secret underground river, Finglas Wood Stream, which flows right beneath their school. “

For further exploration and information, this video from Urban Tales RTÉ One has a good story about Dublin’s Hidden Rivers, covering the history of the rivers, mapping, and even a little subterranean exploration. Worth a watch.

Vanport Mosaic

Jason Kingarchaeology, art, case study, city, cultural, explorations, history, infrastructure, lakes, maps, oregon, photography, places, portland, streams, wetlands2 Comments

Building on my recent post about the anniversary of the catastrophic flooding of Vanport, I had the opportunity to visit some of the events at the Vanport Mosaic Festival from May 25-June 5. One highlight was a series of tours being offered as part of the events on Memorial Day weekend. The tour started at the Portland Expo Center and looped through key areas of the site, and it was exciting to get access to a few areas that are typically off-limits to people on a regular basis. It was also available as a self-guided walking tour, so they had maps for referencing key Vanport locations overlaid with current conditions

The back side of the map is supplemented with imagery of sites along the route, giving a feel for what it was like during the height of Vanport. It’s interesting to see these spaces and activities from 70 years ago, and for the most part discover that few traces of this still exist on-site.

The tour took a bit over an hour, and was led by Clark College professor of geography Heather McAfee, who layered stories and facts onto the tour, and demonstrated a passion for the need to tell the stories of Vanport more widely. While I wished we were able to hop out and explore a bit more, there were a few stops along the way, including this kiosk at one of the parking areas.

The trail adjacent to the site led Force Lake, one of the amenities of the original Vanport community that was formerly adjacent to the original Recreation Center, and had beaches at the margins. The perimeter is now overgrown and a large wetland zone that is mostly inaccessible except from some narrow paths or to golfers on the west side.

Those other uses are a part of the story. South of the kiosk is a good orientation to the current land use of the majority of the Vanport site today with the western portions occupied by Heron Lakes Golf Course and portions of the east side of the site occupied by Portland International Raceway (PIR), making most of the site not publicly accessible.

Track at Portland International Raceway (PIR)

Both of these uses contribute to the lack of remnants that remain from the original Vanport site. As our tour wove between the two atop short levees, we struggled to look from map to site and make any meaningful connections, so disconnected these areas were from their original site, with staring golfers wondering why a seemingly lost tour bus was lumbering around in the middle of nothingness as they went about their rounds.

One area that was protected, through the advocacy of groups wanting to preserve some remnant, the old foundation of the original Theater is still visible on a small margin adjacent to one of the sloughs, protected from construction of PIR (Another remnant area of roadway, a portion of North Cottonwood Street) was incorporated into the straighaway of the racetrack). While indistinct, even this tracery of crumbling foundation serves as a powerful marker, even more so due to the almost complete erasure. Many on our group walked on the surface, paused in a moment of silence, and then moved on. It seems odd, but it had a power, and seemed almost sacred, becoming a tangible touchstone for the past.

Remnant foundation of original Vanport Theater building

McAfee (here pictured) used this location, pointing up at the top of a tree to show the relative height of the floodwaters, which were between 22-28′ high depending on where on the site one stood. As McAfee mentioned, people came into the theater to warn of the breach, shouting:

“The Dike has Broke!”

Seeing this and imagining a water line many feet above your head, coupled with the fact that there was a direct sightline here to the original railroad embankment breach point along the western edge of the site, it hammered home the immensity of the event. It also left me in amazement that even more people hadn’t perished.

The southern apex of the tour swung by Drainage Pump No. 1, which was built in 1917 and worked to remove water from the interior of the levee bottoms. While it helped slow the flood a bit, the fact that it pumped water outside into already swollen creeks meant that it was fighting a losing battle. The pumps still work to dewater the interior the areas today as part of the larger drainage system.

The tour looped to the southeast and a second breach point, then wove back by the original site entrance along Denver Court before returning to the EXPO center. One stop adjacent was a larger wetland area, with another public sign adjacent to the dogpark that also tells the story of Vanport.

Additional information marker from Oregon Travel Information Council

The Vanport Wetlands were adjacent to the site, nestled between PIR and the original Vanport site, and the EXPO center to the north. These and are protected today and support a range of wildlife, according to the Travel Oregon site: “This is an excellent site for waterfowl in winter, and southbound shorebirds in late summer, including Pectoral Sandpiper. Summering ducks include Cinnamon and Blue-winged Teal. Many swallows forage over the water in season. Check the wooded edges for warblers, vireos, and tanagers. Yellow-headed Blackbird has nested here. Red-shouldered Hawk appears occasionally, while American Kestrel, Red-tail Hawk, Osprey, and Bald Eagle are expected. Another 0.5 mi NW on Broadacre is Force Lake, a good place to view migrant grebes, ducks, and shorebirds.”

Vanport Mosaic Exhibits

At the EXPO center post-tour, there were a number of exhibits and groups showcasing topics related to Vanport, social & environmental justice, arts, and culture. The Vanport exhibit was a chance to explore many of the themes around Vanport flood, not just as a historical retrospective but as a way to use this to have new conversations around race. From the site:

“Join us for two weeks of memory activism opportunities, to explore and confront our local past and recent history of “othering” and its tragic consequences. Through exhibits, documentary screenings, tours, theater, and dialogues we will celebrate the lessons of resilience and resistance as defined and told by historically oppressed communities.”

According to this article about the exhibit from OPB, quoting Laura Lo Forti, the Vanport Mosaic co-founder and co-director:

“…it’s important to remember because I feel like we are experiencing yet another wave of collective historical and cultural amnesia.”

Lots of interesting side stories, including learning more about Levee Ready Columbia, working to protect from flood risk in the context of development and climate change in the slough today, as well as finding all the ways to access some local waterways via the Columbia Slough Watershed Council’s ‘Paddlers Access Guide‘. From the artistic side, a few related events include a documentary of Portland stories around trees, Canopy Stories, and a cool project exploring stores of place through music from the Portland Jazz Composers Ensemble “From Maxville to Vanport”. Similar geography, the Maxville Heritage Interpretive Center highlights a fascinating slice of Oregon history, and many other stories can be found via the Oregon Heritage Tradition, which “recognizes events that are more than 50 years old, reflect Oregon’s unique character, and have become associated with what it means to be an Oregonian.” Lots more folks at the event, so this is just a snapshot of a few.

Additional Stories

For a more permanent look at some of the art that looks back at Vanport, you take the yellow line north and stop at the Delta Park/Vanport MAX Light Rail Station. From the TriMet site outlining the Public Art on the Yellow Line, there are a number of elements that reference Vanport. Artist Linda Wysong was the primary creator of this stations installation, built in 2004. Elements include foundation remnants embedded in sidewalk, and a range of other specific elements.

These mosaic tile (the original Vanport Mosaic?) of community maps overlay the current Delta Park site onto the city grid of Vanport. Another map shows local river context within the location of the station.

There are also these beautiful bronze railings, which are a nice touchand easy to miss if you’re not looking, featuring “cast artifacts from the Chinookan culture, Vanport and the Portland International Raceway.”

Another piece that slipped my attention was some “CorTen steel sculptures recall rooftops adrift in the 1948 floodwaters”. There are also works by Douglas Lynch and Timothy Scott Dalbow are reproduced in porcelain enamel on steel, and “…a cast-bronze scupper channels stormwater into the bioswale below.” Lots I missed as it also seems like there an adjacent water quality pond a sculpture called “Waterlines” which had “Massive steel arcs allude to the engineered landscape and Liberty ships made by Vanport residents” as well as a “glowing monolith of stone, steel and acrylic symbolizes the unity of human and natural worlds.” Guess I need to make another visit.

The stories of Vanport are told in multiple locations, with the help of groups like Vanport Mosaic and local artists. However, as mentioned in the OPB story, our “collective amnesia” about historical events, especially those that involve racial inequities and displacement, requires us to first understand and next confront these narratives. As I talked with people around Portland, it was a mixed bag of whether people even knew about Vanport (many had not) or had any real knowledge of the significant (many, myself included, had not). Hopefully the Vanport Mosaic Festival continues, and energy around more ways to discuss, celebrate, and interpret this spatially, so that these hidden histories and made more visible and persist.

Origin Point

Jason Kingart, city, explorations, general, history, landscape, maps, oregon, photography, places, portlandLeave a Comment

We take for granted much of the modern system of mapping and cartography. In the United States, this system is very much derived from our Jeffersonian grid, established in the late 1700s, and expanded along with US western expansion, this (mostly) unwavering net draped over the country as part of the Public Land Survey. I’ve written previously about the General Land Office (GLO) Cadastral Survey, in more general terms, but in that post, I mentioned a unique feature in Portland — the location of one of the few starting points — the 0,0 point which started the mapping for the entire Pacific Northwest on June 4, 1851.

In the most lovely case of serendipitous map-nerdiness, this point has been protected and celebrated, and is thus both visible and accessible by visiting Willamette Stone State Heritage Site in Northwest Portland. A quick drive from downtown Portland, for anyone remotely interested in maps and Portland history it’s a simple trip up Burnside and winding along the back side of Forest Park.

I’ve been staring at the GLO maps for years, and knew it existed but had yet to visit this spot, so the hint of a nice Spring day last weekend was a pretty good opportunity for a short walk and to check this off my list. A small pull-out off of SW Skyline Drive opens up to trailhead, with a informational board offering a brief introduction that outlines the purpose of the park, and some background on the survey, including a sketch by Roger Cooke showing an illustration of the surveyors at work.

From a short blurb on the sign:

“This short trail leads to the Willamette Stone, the surveyor’s monument that is the point of origin for all public land surveys in Oregon and Washington.”

The monument itself is simple. A short walk through forest, a few steps down and a square paved zone, measuring 20×29 feet, surrounded by benches and immersed in a remnant of northwest forest. From the Oregon Encyclopedia: “The surveyors selected a high point on a ridge along the Tualatin Mountains (known today as Portland’s West Hills) for the intersection of the meridian and base line and the location of the survey initial point established on June 4, 1851. Known later as the Willamette Stone, the first marker placed at the survey point was a cedar post. It was replaced in 1888 with an obelisk marker, but the stone marker and bronze plaques were vandalized in 1951, 1967, and 1987. A stainless-steel marker, set into the original obelisk, was rededicated in 1988. The Willamette Stone site is now enclosed in Willamette Stone State Park near Northwest Skyline Boulevard. “

A plaque provides more information, and the marker (a stainless steel version that was installed after other had been vandalized), with the words ‘Initial Point’ of the Willamette Meridian with the T1N/T1S marking townships above and below, and R1W/R1E marking their east/west counterparts. It was a sunny day but early afternoon was casting deep shadows on the spot, giving it an austere, and somewhat ominous feel. It felt, to me somewhat sacred.

The Willamette Stone Park monument captures some of element of the survey in subtle ways. Embedded metal strips highlight markings on the ground surface, representing the meridian and baseline, a typical township broken into it’s requisite allotment of 36 equally spaced, 640 acre sections, ready for development.

It’s interesting for something so innocuous to hold such power, a simple disc of metal that references something much larger, and more meaningful. The hours I’ve spent staring at the maps derived from this point and the rich history that unfolds. It includes both a snapshot of what existed in the mid-1800s, but by extrapolating back as well to Native settlement and use, shows also a network of pathways worn to common points – a boat launch, a ferry, a significant landmark. These hints of pre-colonial use were shaped for many years, and some have persisted in our urban development – a path turning from a trail now a road with some odd, informal alignment. Ecological mosaics now transformed, consisting of coniferous forests and deciduous lowlands, with marshy margins near meandering rivers whose shorelines continue to weave their way through the pull of northward flowing water. And, all of those now disappeared waterways – the buried creeks, the long forgotten lakes, the now filled wetlands.

Township 1 South, Range 1 E (the Willamette Stone would be the upper left hand corner of this map)

Sitting on one of the benches, I close my eyes and transport myself back to this spot in 1852. I remark on the integrity of some of the remaining verdant ecosystem in this unassuming spot. The verticality of Douglas Fir spires towering skyward, mixed with moss-draped Bigleaf Maple and understory Vine Maple pushing their bright green spring leaves. On the ground, dense clumps of Salal weave around in abundance, punctuated with the complementary textures of Sword Fern and Oregon Grape, lighter margins of Snowberry and Currant. And, to mark the season with a punctuation mark, the fleeting display of Trillium.

Then, slowly, as I peer around, at the edges, I spy a hint of invasive English Ivy and English Holly (both of which were absent from this ecosystem of 170 years ago), beginning to creep out to the margin of my vision. A witness to our human impacts. Panning right, the faint etchings of guy-wires intrude into the viewshed amidst the trees. I’d been so focused on the ground, and the stone, head down focusing on the monument, I’d been unaware of this neighbor. I slowly follow their paths in an about-face, craning my neck straight up to the apex of the radio tower close-by. Not looming, but its red and white paint, and geometry in sharp contrast to the lush greenery.

Thus the scene, as the origin point, took on a double meaning. Although lush and natural on the surface and very much of the place in the Oregon landscape, this survey point was also the origin of our rapidly changing environment. This is evident in the burgeoning city that exists today, and the irreparable impacts on ecology and hydrology that make it barely legible from where it all started. The origin point of our discovery, what we have now experientially only in maps as a record, also being the origin point of our changing landscape and humanity.

The bench I sat on had double meaning also. Surrounding the monument, these contained the names of significant surveyors relevant to this westward documentation. William Ives was responsible for running the Meridian northward towards the Puget Sound, and Eastward along the Baseline as well, according to the history of the Oregon Land Survey John B Preston is also acknowledged, as the first Surveyor General of the Oregon Territory and Western US, his name is pervasive, affixed to many of the GLO maps. And finally, one dedicated to C. Albert White, who was at BLM surveyor with the General Land Office who started in the 1940s, and is know as an expert in cadastral surveying history, which is seem in his 1983 publication, ‘The History of the Rectangular Survey” which is the definitive tome on the Public Land Survey, and fitting for him to be celebrated here as well.

A map excerpt shows these ubiquitous gridlines – the work of Ives and Preston notably on, “A Diagram of a Portion of Oregon Territory,” from 1852. This map highlights this point where the Baseline runs east and west from ocean to the state borders, and the Willamette Meridian runs north-south from the southern border of Oregon up to the US/Canada border. The origin made manifest.

It’s amazing how this GLO survey left an amazing resource for hydrology of cities that were relatively undisturbed, as these surveys were done in a relatively youthful United States, and in the west the mapping in the 1850s was done concurrent with the establishment of many settlements. The resulting maps show small, nascent grids, which predate much of the late 19th and early 20th creative destruction that forever changed the landscape and led to hidden hydrology. It’s good to know your origin story. And in this case, the origin is close at hand.

A Place for the Senses, Part 2 – Soundscapes

Jason Kingart, creeks, cultural, explorations, history, infrastructure, language, maps, rivers, soundscape, streamsLeave a Comment

A few months back, I posted part one of this dual post on sensory ways of interpreting spaces and art with a focus on the amazing work around Smellscapes. Part two, as advertised, will shift gears a bit, to think about Soundscapes, and how audio can be used to illuminate places, tell stories, and engage the senses in new ways. And there’s a lot of exciting stuff happening in this space, and this will barely scratch the surface of what people are doing, but I am focused mostly on that which is relevant to the agenda of hidden hydrology, or in ways that are not directly relevant, could inspire some new methods of intervention and interpretation.

The idea of sound is expressed in a number of interesting ways, and more importance is placed on soundscapes in design, or the larger urban sphere, and the impacts of things like noise and how it impacts humans and other species. Or conversely, it may just be confronting the dilemma posed by White Noise, in their article about innovative sound artists “The Trouble With Sound Is That It’s Invisible.” New ways of thinking about these topics more holistically show up under terms like Acoustic Ecology, or Sonic Ecology, which thinks about it from a broader way of thinking. From the abstract of a introductory paper on Soundscape Ecology , the idea for the authors is that:

“The study of sound in landscapes is based on an understanding of how sound, from various sources—biological, geophysical and anthropogenic—can be used to understand coupled natural-human dynamics across different spatial and temporal scales.”

A great resource on the topic I’ve found is The Acoustic City, which is a book/CD and website focused “on sound and the city… The book comprises five thematic sections: urban soundscapes with an emphasis on the distinctiveness of the urban acoustic realm; acoustic flânerie and the recording of sonic environments; sound cultures arising from specific associations between music, place, and sound; acoustic ecologies including relationships between architecture, sound, and urban design; and the politics of noise extending to different instances of anxiety or conflict over sound. This innovative essay collection will be of interest to a wide range of disciplines including architecture, cultural studies, geography, musicology, and urban sociology.”

INTERACTIVE SOUNDSCAPES/WALKS

There’s a number of leaders in the field, but I will lead off with one of the rock-stars of this sub-genre that is doing inspired work around water is Leah Barclay, who seems to be everywhere doing amazing work. From her bio: “Leah Barclay is an Australian sound artist, composer and researcher working at the intersection of art, science and technology. She specialises in acoustic ecology, environmental field recording and emerging fields of biology exploring environmental patterns and changes through sound. Over the last decade her work has focused on the conservation of rivers, reefs and rainforests through interdisciplinary creative projects that inspire communities to listen.” One such installation is called Hydrology, which is a collection of sounds “…recorded using hydrophones (underwater microphones) in freshwater and marine ecosystems across the planet.” and River Listening, which is “an interdisciplinary collaboration designed to explore the creative possibilities of aquatic bioacoustics and the potential for new approaches in the conservation of global river systems.” Her work is also available at this interesting site 100 Ways to Listen, from Queensland Conservatorium Griffith University, which has a ton of great soundscape info, focusing on “exploring the art and science of sound and documenting a decade of innovative music-making.”

The idea of interactive sound around water has a few specific precedents worth focusing on hidden hydrology directly. A project I mentioned a few years back is relevant, SCAPE’s work in Lexington, Kentucky. which featured that of a series of listening stations and a self-guided ‘Water Walk‘ for their project around Town Branch Commons, to tell the story giving users: a broad understanding of the biophysical area around the Town Branch, reveals the invisible waters that run beneath the city, and demonstrates some of the impacts each resident of Lexington can have on the river and its water quality. By sharing how water systems and people are interrelated—both locally and globally—the Town Branch Water Walk makes stormwater quality relevant, linking it with the history, culture, and ecology of the city.”

Another project that really embodies the potential of this is a School of the Art Institute of Chicago (SAIC) project from professor Linda Keane and artist Eric Leonardson called RiverWorks, which is described as “…an interactive transient sound mapping and community engagement series of classes that reimagines and visualizes the sustainable world above and beneath the surface of the Chicago River. Challenging engagement with water, water habitats, water conservation and water quality, students activate new connections and thinking about the Chicago River as a healthy, working and recreational ecology. Inspired by John Cages’ 1978 Dip in the Lake series of acoustical experiences throughout Chicago, the course captures sounds of water, water use and misuse in the city.”

Students explore and create art, around walking, sensing, and as a project called River Listening, which is exciting as an “interdisciplinary collaboration examines creative possibilities for marine bioacoustics and the potential for new approaches to the conservation of urban global river systems… students fabricate hydrophones for listening for wildlife diversity below the river’s surface. Connecting invisible riverine life with urban water infrastructure, River Listening activates familiar places with unfamiliar information creating immersive spaces. Students experience interactive listening labs and document field recordings in preparation for sound maps, spontaneous performances, and installations that creatively use everyday technologies.”

An article in Open Rivers Journal from 2017 by Christopher Caskey provides a fascinating context for this work. “Listening to a River: How Sound Emerges in River Histories” which posits that environmental historians could use sound more to develop inquiry into environments. Drawing from Peter Coates article “The Strange Stillness of the Past: Toward an Environmental History of Sound and Noise”, in which Coates “argues both for “knowing nature through sound” and “picking up nature’s voices” in his case for analyzing sound in environmental history”, the article focuses this idea on rivers, ending with this important conclusion:

“Rivers are particularly auditory places. They make their own sounds and they have played important roles in influencing aural culture. Whether as a storytelling device, as part of an analysis, or even as an inclusion for the sake of posterity, the sounds of a river, both past and present, are worth documenting as part of the historical record.”

SOUND MAPS

An interesting strategy is to provide maps of sounds, which tie the auditory with the spatial, as mentioned in this abstract “growing research initiatives that take up soundmapping as a way of inquiring into pressing spatial, geo-political and cultural issues primarily in cities and also in the endangered wilds.” This happens in a few ways, but can include modern soundscapes, where there are no shortage of maps and sites documenting the sounds of places, including global maps, such as this one from Cities and Memory, or Locus Sonus and to cities as diverse as Charlottesville, Virginia, Florence, Italy, Shanghai, China, and Montreal, Canada (below)

Each map comes with its own agenda, which ranges from nature sounds, biodiversity, urbanization, transit, social spaces, art or even places of quiet. The key, is that these maps have to have some agenda or viewpoint and have some innovative delivery method, otherwise, they will be boring, as pointed out in this great opinion piece on the subject, “Sound Maps in the 21st Century: Where Do We Go From Here?”

The idea of mapping historical sounds does have a viewpoint, as it allows ways of connecting to the past, and appreciating the changing nature of urban environments. One of my favorites is The Roaring Twenties, which gives an extensive spatial overview of NY City by coupling noise complaints and newsreels with places and sounds – giving a hint of a place, more focused on the man-made than natural sounds, but the section ‘Harbor & River’ connects a bit with the hydrology, along with some info on Sewer/Water Construction.

Another extensive example is the London Sound Survey, which is a really ambitious project (more here). There’s interesting maps of a range of topics both contemporary and historical, including the hydrological, focusing on both exportation of the Thames Estuary, and a map of London’s waterways “An auditory tribute to Harry Beck’s Underground map, the skeleton which has long lent shape to the city in the minds of Londoners. Here sounds were collected from along London’s canals and lesser rivers.”

MUSIC

A number of interesting projects focus on music, which can be used to creatively engage with the environment. Re:Sound is an experimental music series which explores the relationship between forgotten spaces, sound abstraction and the natural environment.

The ClimateMusic Project is another sort of endeavor with a larger mission to “…enable the creation and staging of science-guided music and visual experiences to inspire people to engage actively on the issue of climate change. As an analogy for climate, music is familiar, accessible, and—for most people—much easier to relate to than articles or lectures. We created The ClimateMusic Project to harness this universal language to tell the urgent story of climate change to broad and diverse audiences in a way that resonates, educates, and motivates.”

The use of apps is an interesting option as well, melding GPS and music to orchestrate unique experiences that change and evolve as one moves through space. One I’ve always been excited about is by Bluebrain from 2011 and their installation“‘Central Park (Listen to the Light)’ … a site-specific work of music that responds to the listeners location within the stretch of green of the same name in New York City… work by tracking a users location via the iPhones built-in GPS capabilities. Hundreds of zones within the landscape are tagged and alter the sound based on where the listener is located in proximity to them. Zones overlap and interact in dynamic ways that, while far from random, will yield a unique experience with each listen. The proprietary design that is the engine behind the app stays hidden from view as the melodies, rhythms, instrumentation and pace of the music vary based on the listeners’ chosen path…. The app is the work itself. A musical ‘Chose-Your-Own-Adventure’ that does not progress in a linear fashion but rather allows the listener to explore the terrain and experience music in way that has never been possible before now. “Read more about this in a NY Times article ‘Central Park, The Soundtrack‘ from when it was released as well, and check out a short video here.

Phantom Islands is an interesting work that exists in the peripheral vision of Hidden Hydrology. Developed by experimental musician Andrew Pekler, which was part of an oddly intriguing show called Fourth Worlds, Imaginary Ethnography in Musical and Sound Experimentation. From the site: “Phantom Islands are artifacts of the age of maritime discovery and colonial expansion. During centuries of ocean exploration these islands were sighted, charted, described and even explored – but their existence has never been ultimately verified. Poised somewhere between cartographical fact and maritime fiction, they haunted seafarers’ maps for hundreds of years, inspiring legends, fantasies, and counterfactual histories. Phantom Islands – A Sonic Atlas interprets and presents these imaginations in the form of an interactive map which charts the sounds of a number of historical phantom islands.”

A screenshot of it is below of one of the ‘entries’, but you really have to go experience it, let loose and have fun.

And, closing the loop on the musical side, there’s a fun Billboard article ‘10 Songs About Rivers‘ which, I feel, focused a bit much on the contemporary and missed some classics, but fun to think about. The BBC has plenty of interesting music, such as the session on Playing the Skyline, in which “musicians look at how the land meets the air and imagine it as music.” And if we’re getting fully into the influence of environmental on music, a series of works by composer Tobias Picker inspired by Old and Lost Rivers, and even a Lost Rivers Opera from the Czech Republic, which i had a link to in the past but is now no longer working (anyone help there?)

So much more to explore, but this at least provides a primer on sound, and I’m excited to see more about how people are using this media to explore and expand our awareness, specifically focused on hydrology. Any ideas in that realm, please feel free to comment.
