As the Waters of Lake Powell Recede
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.
