1964 Map of Tenmile Flat

About this map

Tenmile Flat and the surrounding plateau regions of Garfield County are defined by a complex drainage network that includes Harris Wash, Phipps Wash, and Cottonwood Wash. In the mid-1960s, this landscape was navigated via the Sheffield Road and the Old Sheffield Road, which provided access to high-altitude features like Little Spencer Flat and Big Spencer Flats. Human presence is marked by isolated Corrals, a Borrow Pit, and a Radio Facility, suggesting a landscape used primarily for livestock grazing and utility infrastructure. Notable geological features like Deadman Ridge and Halfway Hollow partition the terrain, while reliable water sources such as Tenmile Spring served as critical landmarks for those traversing the high desert flats.
