About this map

The arid borderlands of the Yuha Basin are captured in detail during the late 1950s, revealing a landscape defined by natural geological formations and sparse transit routes. The presence of significant Shell Beds and prominent landmarks like Sunrise Butte and the Yuha Buttes illustrate the prehistoric lakebed history of this Colorado Desert region. Transportation across the basin is limited to a network of primitive routes, most notably the Yuha Cutoff and various Jeep Trails that navigate between West Mesa and the expansive Pinto Wash.

Along the eastern edge of the survey, man-made water management becomes visible with the W Side Main Canal and Dixie Drain 2, marking the transition from the dry Yuha Wash to the irrigated agricultural lands of the Imperial Valley. The southern margin is strictly defined by the international boundary between the United States and Mexico, where the desert terrain remains largely undisturbed except for a few isolated features like a Gravel Pit and the high point at Hump.
