Glen Canyon

Glen Canyon's sculpted sandstone walls, narrow side canyons, and winding river corridor surround Lake Powell, carved by the Colorado River through Navajo and Wingate sandstone over millions of years.

About Glen Canyon

Glen Canyon is the broader sandstone canyon system carved by the Colorado River through Navajo and Wingate sandstone, much of it now submerged beneath Lake Powell following the construction of Glen Canyon Dam. Protected today as Glen Canyon National Recreation Area, the canyon includes stretches of river both above and below the reservoir, along with significant archaeological and cultural resources tied to the region's long Indigenous history.
