As the Waters of Lake Powell Recede
Season 10 Episode 1007 | 26m 46s | CC
The Colorado River was dammed at Glen Canyon in the early 1960s. The resulting reservoir, Lake Powell, is the second largest reservoir in the United States. As a prolonged drought grips the southwest, the lake is shrinking. The falling water levels reveal a wonderland of canyons from angles never before seen and the new landscapes reveal fragments of ancient peoples who made Glen Canyon home.
