2017 Map of Luman Rim

About this map

Luman Rim and its namesake Luman Butte define this high-desert landscape in Sweetwater County, where the topography of the Red Desert transitions through a series of dramatic draws and basins. This modern survey illustrates a quiet corner of the Great Divide Basin, characterized by ephemeral drainages such as Bush Creek and Bear Creek that carve through the arid terrain. The map highlights the isolation of features like the Buffalo Hump and its surrounding Buffalo Hump Basin, which serve as significant landmarks for those navigating the backcountry. Infrastructure is limited to essential regional arteries including the Tipton-North Rd and Co Rd 4-20, reflecting the area's continued use for open-range grazing and natural resource access. The detailed contouring provides a clear view of the erosion patterns at Cronin Draw, offering insight into the geological character of the Wyoming high plains.
