1970 Map of Prehistoric Rim

About this map

Prehistoric Rim and its distinct geological shelf dominate this section of the Wyoming desert in Sweetwater County. The terrain is characterized by a network of drainage systems, including the prominent Skull Creek to the west and Sand Creek cutting across the center, illustrating how seasonal water has carved the landscape. A notable human trace in this 1970 survey is a solitary drill hole located in section 28, indicating mineral or resource exploration in the high desert during the mid-20th century.
