Glen Canyon, Arizona
Glen Canyon was formed by the Colorado River and is located between Lake Powell and Lee's Ferry, in Northern Arizona. Originally, the canyon stretched about 100 miles further upstream, into what is now Utah’s Lake Powell, a large reservoir formed by the construction of Glen Canyon Dam in 1964. The Navajo name for the canyon is not certain but it may be “Tséyi'” meaning "a place deep in the rock." The name Glen Canyon was registered in 1869 by John Wesley Powell, the Anglo explorer after whom Lake Powell is named.
