2021 Map of Formaster Well

About this map

Formaster Well sits at the heart of this Mohave County desert landscape, where water management and seasonal drainage define the local topography. This 2021 survey by the U.S. Geological Survey captures the modern configuration of cattle country and high-desert terrain, characterized by prominent landmarks like the Black Knolls and the sweeping Upper Clayhole Valley. The map details a network of vital waterways and catchments, including Sandridge Wash, Clayhole Wash, and Flattop Reservoir, which reflect the area's ongoing reliance on limited water resources. Connectivity in this sparsely populated region is maintained by a few key corridors such as Co HWY 5, Co HWY 241, and the historically suggestive Navajo Trail Rd. The layout of township and range lines, including t40n r8w and t39n r7w, provides a clear framework for land management in this section of the Arizona Strip.
