1963 Map of Potter Mountain

About this map

Pio Moses Ranch sits in the high desert of Sweetwater County, marking a rare human outpost in a landscape dominated by complex drainage systems and high ridges. Established grazing and water management are evident across the terrain, with features like Potter Mountain Reservoir and Pio Reservoir supporting livestock in an arid environment. The map details a sophisticated network of seasonal watercourses, including Dry Canyon, Brooks Draw, and West Draw, which carve through the elevations of Potter Mountain and Elk Butte. Isolated resources such as Jim Washum Spring and Laney Spring provide vital landmarks for those navigating the high country. To the south, the terrain drops toward Rifes Rim and the winding course of Salt Wells Creek, while scattered markers for a Gas Well and Drill Hole point to early exploration of the region's mineral potential.
