2015 Map of Prehistoric Rim

About this map

Prehistoric Rim and the dramatic escarpment of Skull Creek Rim define this arid landscape in Sweetwater County. The terrain is characterized by the deeply incised drainage of Haystack Wash, which winds through a series of high ridges and plateaus. This 2015 survey reflects the modern management of the high desert, where access is dictated by primitive routes like Blm-4412. The absence of developed towns or settlements highlights the isolation of this corner of the Great Divide Basin, focusing instead on the prominent natural landforms like East Fork Point that have served as navigational landmarks for generations of travelers across the Wyoming plains.
