1985 Map of Cathedral Canyon

About this map

Lake Powell and the winding course of the Colorado River dominate this 1985 landscape on the border of Utah and Arizona. The map depicts the complex intersection of the Navajo Indian Reservation and the Glen Canyon National Recreation Area, highlighting a region defined by dramatic elevation changes. Massive landforms such as Cummings Mesa rise above the deep incisions of Cathedral Canyon and Wetherill Canyon. Small natural landmarks are meticulously charted, including named spans like Carrot Top Arch and Keyhole Arch, alongside prominent high points such as Cathedral Butte. The surveyor’s detail captures the early years of the reservoir's maturity, showing the pool elevation at 3,700 feet where the desert floor meets the rising waters of the Colorado.
