Sandy River Delta lies outside Troutdale, Oregon, and was home primarily to the Clackamas tribe. Lin selected this location, in part, because it provided a narrative of successful ecological rejuvenation. The Sandy River Delta Dam, built in the 1930s, was removed in 2013, reconnecting the Sandy and Columbia Rivers. There is also an ongoing riparian reforestation program of 17 acres in and around the river that includes a mix of native trees and shrubs. The site includes a bird blind, which has an elliptical structure approximately twelve-feet in diameter. It is perched on the precipice of the river’s original channel which will gradually be redirected now that the dam is gone. Inside, the wooden slats of the bird blind are ten-feet tall and engraved with a list of those species observed and recorded by William Clark. The text is oriented vertically and lists 134 birds and animals, the date encountered, common name, scientific name, and their current ecological status. Planning and construction of the site lasted from 2002 to 2008.
