On Earth Day, members of environmental groups came together to call for cleanup of thousands of abandoned uranium mines in South Dakota and other locations, most of them in Western states. Charmaine White Face of Defenders of the Black Hills headed up this effort and chose the Cheyenne River as a meeting place. She says it’s one of several contaminated areas in the state. SDPB’s Victoria Wicks traveled to find the environmentalists about 20 miles east of Hermosa on Highway 40.
