1986 Map of Mount Trumbull

About this map

The Colorado River carves through the heart of this landscape, marking the dramatic transition from the Shiwits Plateau to the Uinkaret Plateau. This 1986 edition records a territory defined by its extreme verticality and isolation, where historical mining operations like the Grand Gulch Mine and Cunningham Mine established small footholds in the desert. The map captures the meeting of several major protected areas, including Grand Canyon National Park and the Lake Mead National Recreation Area. Significant peaks such as Mount Trumbull, Mount Logan, and Mount Emma dominate the high ground above the Hurricane Cliffs. Along the river itself, treacherous features like Lava Falls Rapids and Separation Rapids are documented, while high points like Snap Point and Kelly Point overlook the vast canyon system.
