1958 Map of Twelvemile Well

USGS Topo · Published 1960

About this map

The Continental Divide winds through this arid expanse of Sweetwater County, marking a high water-parting line above a landscape defined by seasonal washes and significant geological depressions. In the late 1950s, this area was characterized by the sprawling Alkali Basin and fields of shifting Sand Dunes, punctuated by the vital Twelvemile Well. This artesian source served as a critical landmark for those navigating the high plains between the Black Rock Flat and Tenmile Flat.
