Cathedral Rock is a 3,942-foot-elevation (1,202 m) pillar located within Glen Canyon National Recreation Area, in Coconino County of northern Arizona.[3] It is situated less than one mile northwest of Navajo Bridge, and three miles (4.8 km) southwest of Lee's Ferry and the confluence of the Paria and Colorado Rivers, where it towers over 400 feet (120 m) above the surrounding terrain as a landmark of the area. It can be seen from nearby U.S. Route 89A (US 89A) at Marble Canyon. This geographical feature's name was bestowed prior to 1900, and officially adopted in 1969 by the U.S. Board on Geographic Names.[3]

Geology[]

Cathedral Rock is located on the Colorado Plateau. This erosional remnant is composed of red sandstone of the Moenkopi Formation, which was laid down during the Triassic. It is overlain by a Shinarump Conglomerate caprock.[4] Precipitation runoff from this feature drains to the nearby Colorado River, one-half mile to the east.
