The Colorado River passes through Marble Canyon as it flows from Lake Powell to the Grand Canyon. In addition to the canyon, the surrounding scenery features the Vermilion Cliffs, and the historical site of the Lees Ferry crossing, at one time the only place to cross the Colorado for 500 miles. These pictures are from my 2004 visit to Marble Canyon.
