The Animas River flows through the mountains of Southwestern Colorado, through what was once the undisputed land of the Ute people before the encroachment of white miners in the 19th century. In 2015, the EPA was performing maintenance on the abandoned Gold King Mine when it accidentally released three million gallons of wastewater contaminated with heavy metals into the river, turning it a bright orange and threatening agriculture, tourism, and an already “disturbed” alpine ecology.
Animas comprises suspended panels of iron-oxidized steel, aluminum, copper, and lead—all metals that have exceeded EPA tolerances in the river. Each panel vibrates at its own resonant frequency with an intensity that follows real-time data from water quality sensors placed in the river by the USGS and by the Southern Ute Indian Tribe Water Quality Program. Changes in the clarity of the water, invisible indicators of the dissolved metals within it, and the dynamics of its daily and seasonal flows all become sound in the gallery, producing timbral “color” from the river’s continually changing composition.
