About this map

Seminoe Reservoir dominates this high-altitude landscape in Carbon County, its irregular shoreline carving deep into the surrounding terrain. The reservoir is framed by prominent geological features including the long, east-west spine of Horseshoe Ridge, which rises sharply above the southern reach of the water. This 2021 survey illustrates the complex drainage patterns feeding the reservoir, defined by seasonal creeks and deep erosional cuts.

Erosion has shaped much of the local nomenclature, with named canyons like Big Draw, McNees Draw, and Spencer Draw providing natural conduits for runoff from the higher elevations. Smaller watercourses such as Beaver Jimmy Cr and Austin Cr wind through the eastern hills, reflecting the characteristic basin-and-range topography of southern Wyoming. The map provides a precise look at the township and range boundaries that organize this open country, where human impact is largely limited to these drainage-based place names.
