About this map

Alkali Basin and the broad expanse of Black Rock Flat define this high desert landscape in Sweetwater County during the mid-1980s. The terrain is characterized by intricate drainage patterns and geological transitions, where ephemeral watercourses like Black Rock Creek and Twelvemile Gulch wind through the arid plains. A scattering of seasonal lakes and ponds dots the basin floor, reflecting a landscape shaped by internal drainage and high mineral content.
