1952 Map of Dinnehotso

About this map

Dinnehotso and its Trading Post serve as the primary human settlement in this high desert landscape, mapped during the early 1950s when agricultural efforts were supported by an Irrigation Ditch and Laguna Creek. The survey highlights the significant industrial presence of the Monument No 2 Mine, a Cold War-era uranium operation developed in cooperation with the Atomic Energy Commission. Beyond the industry, the terrain is dominated by the striking geologic formations of Monument Valley, including Yazzie Mesa, Rooster Rock, and Meridian Butte. Water is a critical and sparse resource, marked by scattered springs, a Windmill, and drainage systems like Gypsum Creek and Cane Valley Wash. The map documents the vast, open expanses of Greasewood Flat and Chinle Valley, where the boundary between Apache County and Navajo County meets the Utah-Arizona state line.
