2021 Map of Black Rock Flat East

USGS Topo · Published 2021

About this map

Alkali Basin and the expansive Black Rock Flat characterize this high desert landscape in Sweetwater County. The terrain is defined by seasonal drainage patterns, where Alkali Draw leads into the basin, and Black Rock Cr cuts across the southern sections of the survey. The mapping reveals a remote region where human infrastructure is limited to primitive thoroughfares like Co RD 4-21 and Co RD 4-82. To the southeast, the topography drops into Twelvemile Gulch, providing a detailed look at the drainage systems that shaped this portion of the Wyoming basins during the early twenty-first century.
