2021 Map of Buffalo Hump Basin

About this map

Buffalo Hump Basin defines this high-desert landscape in Sweetwater County, where the terrain is marked by seasonal drainage and broad, arid flats. The 2021 topography reveals the hydrologic character of the region, centered around Buffalo Hump Lake and the winding course of Bush Cr to the north. Further south, the map details the depression of Alkali Basin, leading toward the natural drainage of Alkali Draw. Human presence is sparse and primarily infrastructure-based, with local routes like Bar X Rd, Co Rd 15, and Co Rd 4-21 providing the only reliable access through the expansive Bureau of Land Management territory. This survey reflects the modern state of Wyoming's interior basins, documenting the exact contours of the land and its limited water sources.
