About this map

The Continental Divide winds through this high-altitude landscape of Sweetwater County, Wyoming, as it was surveyed in the late 1950s. The terrain is a complex arrangement of dry basins and elevated flats, characterized by the expansive Black Rock Flat and the depressions of Alkali Basin. A rare and vital water source for the region is found at Twelvemile Well, an artesian spring located near the head of Twelvemile Gulch.
