1968 Map of Twelvemile Sink

USGS Topo · Published 1980

About this map

Twelvemile Sink defines this corner of Sweetwater County, a high-desert landscape marked by the deep erosional cuts of Eighteenmile Canyon and Buckhorn Canyon. This 1968 survey (with 1978 updates) illustrates the vital role of water and infrastructure in this arid region, showing the solitary Eighteenmile Well and a Flowing Well as critical landmarks for ranchers or travelers. The Lincoln Sweetwater Road serves as the primary artery through the terrain, connecting remote points across the desert. Evidence of industrial exploration is present through isolated labels such as a Pit and a Drill Hole, reflecting the mineral and resource prospecting common in this part of Wyoming during the late 1960s. The map provides a precise look at the township and range system at the convergence of T. 24 N. and T. 25 N., where the land falls away into the branching reaches of Twelvemile Canyon.
