About this map

Navajo Indian Reservation lands dominate this mid-century survey of the Arizona high desert, centered on the striking geological formation of Shinumo Altar. The landscape is defined by the massive Echo Cliffs and the rising Kaibito Plateau to the east, which frame the long corridor of Cedar Ridge Valley. Human presence is sparse but centered on the Cedar Ridge Trading Post, a vital outpost for commerce and communication in this arid region during the early 1950s.

The distribution of water sources across the sheet—ranging from named washes like Hogansani Wash and Tatahatso Wash to man-made catchment features like McClellan Tanks and Blue Moon Reservoir—illustrates the critical importance of water management for livestock and survival. Distinctive landforms such as Bodaway Mesa, Tooth Rock, and the Bodaway Mountains provide essential navigation landmarks across the broad expanses of the Rock Corral Bench.
