2012 Map of Twelvemile Sink

About this map

Twelvemile Sink characterizes this high-desert region of Sweetwater County, where the landscape is defined by its subtle drainage patterns and sparse network of transport routes. The 2012 survey illustrates the remote character of the basin, dominated by extensive drainage systems that feed into the central sink. Human presence is evidenced primarily by two significant unpaved corridors: Monument Butte Rd and 18 Mile Rd, which cross the terrain to connect distant ranching or resource areas. The lack of traditional settlements or structures emphasizes the open, undeveloped nature of the Wyoming interior during the early 21st century, making it a critical record for those studying the intersection of geology and historic public land use.
