About this map

The Colorado River carves through the heart of this landscape, marking the dramatic transition from the Glen Canyon National Recreation Area into the northern reaches of Grand Canyon National Park. Revised in 1970, the map documents the arrival of the Glen Canyon Dam and the rising waters of Lake Powell, contrasting these modern engineering feats against ancient landmarks like Lees Ferry and the Navajo Bridge.

On the expansive Navajo Indian Reservation, the geography is defined by prominent landforms such as the Kaibito Plateau, Echo Cliffs, and the Vermilion Cliffs. Remote outposts and cultural sites are scattered across the terrain, including Hogan and the Navajo National Monument. The river corridor itself is a detailed register of historical navigation, noting legendary obstacles like House Rock Rapids, Sockdolager Rapids, and President Harding Rapids.
