1988 Map of Formaster Well

About this map

Upper Clayhole Valley defines the southern reach of this 1980s landscape, a high desert region characterized by seasonal drainage patterns and isolated water sources. The map focuses on the namesake Formaster Well, a critical water point for local ranching operations, which also includes a nearby Corral. The terrain transitions from the alluvial fans of Sandridge Wash in the north toward prominent landforms such as Black Knolls and Flat Top. Evidence of land management and transportation is sparse but distinct, featuring a Check Dam on a minor drainage and the path of the Navajo Trail cutting across the western sections. This survey provides a clear view of the arid infrastructure in Arizona's north-central plateau region during the late 20th century.
