The Glen Canyon Dam was completed along the Colorado River in 1966, creating Lake Powell. The lake can hold as much as 25 million acre feet of water, but is currently only at 27%. The photos of that shortage are dramatic.
At 710′ high, it is the 4th tallest dam in the United States.
A look down river at the canyon.
The rock formations around the canyon have some of the distinctive swirls.
Once you cross the bridge you get some dramatic views of the dam, bridge and lake. For those unfamiliar the ‘bathtub ring’ indicates the high water marks.
