1967 Map of Mount Trumbull NE

About this map

Toroweap Valley divides this high-desert landscape, a striking corridor bounded by the rising Toroweap Cliffs and the volcanic terrain of the Uinkaret Plateau. Surveyed in the late 1960s, the map highlights the intersection of public lands, where the Kaibab National Forest meets the northern reaches of the Grand Canyon National Monument. Human presence is sparse, marked primarily by ranching and resource extraction, notably at Graham Ranch and a Cinder Pit near the northern edge. Essential water sources for the region's livestock and wildlife are identified at Witch Pool and Little Toroweap Res. The terrain shifts from the level benches of the Kanab Plateau into the complex drainages of Broad Canyon, illustrating the dramatic geologic transition toward the canyon rim.
