New Tang Exhibition Traces Two Decades of Ecological Repair

The Tang Museum at Skidmore College presents 500 Dams: Art, Ecology, and Radical Care at Anaya Springs, an exhibition tracing a more than two-decade effort to regenerate degraded grasslands in New Mexico through hand-built stone dams and the art, mapping, and ecological research that have grown around the project. The exhibition opens September 26 and runs through January 10, 2027.
For more than two decades, artist Bill Gilbert and landscape architect Anne Nelson have walked the high-desert landscape of Anaya Springs, building low stone dams by hand to slow rainwater runoff, capture soil and seeds, and help grasses and other plants take hold. Historic overgrazing and erosion had stripped vegetation and topsoil from the landscape, reducing its ability to absorb and retain water. What began as a daily practice on land they purchased in 2003 now encompasses more than 1,700 dams, far beyond Gilbert’s original estimate of 500.
Their work at Anaya Springs later expanded through the Survival Kit Collective (SKC), bringing together artists, scientists, mapping specialists, friends, and family to study, document, and interpret the changing landscape.
500 Dams: Art, Ecology, and Radical Care at Anaya Springs brings that experiment into the Tang Museum, where visitors can encounter the work of the SKC members including interactive maps charting Anaya Springs’ watersheds, dams, and plant life; data examining soil moisture and plant diversity; aerial films of creek beds; botanical watercolors; ceramic maps based on the contours of the land and patterns of water flow; a hand-drawn animation of Gilbert and Nelson building a dam; and large-scale adobe works embedded with seeds.
“500 Dams is about the power of personal agency and collective effort,” said exhibition curator Rachel Seligman, the Assistant Director for Curatorial Affairs and Malloy Curator at the Tang. “What began with the simple act of placing a few stones in the landscape has grown to more than 1,700 dams over two decades. By focusing on the small and local, the project shows how sustained attention and care can build resilience, inspire collaboration, and make meaningful change possible.”
Four of the Survival Kit Collective’s eight members will extend the exhibition’s inquiry through public programs at the Tang this fall.
New Mexico artist and educator Ruben Olguin, whose adobe sculptures incorporate native seeds, joins Skidmore sustainability director Tarah Rowse for a Dunkerley Dialogue on September 24.
In November, artist and University of New Mexico emeritus professor Bill Gilbert gives an artist talk followed by a conversation with Charlie Bettigole, a graphic information systems (GIS) specialist and former director of Skidmore’s GIS Center for Interdisciplinary Research; artist Lynn Grimes, whose work combines botanical observation, natural history, and art; moderated by Seligman. The following day, Bettigole leads a beginner GIS cartography workshop, and Grimes leads a flora zine-making workshop.
