2023 Map of Tenmile Flat

About this map

Tenmile Flat and its surrounding plateau systems in Garfield County characterize this portion of the Utah desert as it appeared in 2023. The terrain is defined by wide, relatively level mesas including Little Spencer Flat, Big Spencer Flats, and Seep Flat, which are dissected by complex drainage networks like Phipps Wash and Cottonwood Wash. These geographical features demonstrate the intricate erosion patterns of the region, where seasonal water flow has carved deep into the elevated flats. Human presence is sparse, anchored primarily by the Old Sheffield Rd, which provides one of the few navigational landmarks through the territory. Significant landforms such as Deadman Ridge and the Halfway Hollow drainage offer clear points of reference for those studying the physical geography or tracing historic routes through this portion of the Escalante basin.
