1988 Map of Thomas Reservoir

About this map

Carter Mountain dominates the northwestern horizon of this high-altitude Wyoming landscape, where steep slopes give way to a network of drainage basins. The area is defined by its water management and resource infrastructure, centered on the Thomas Reservoir. This artificial catchment sits at an elevation of 8,485 feet, collecting flow from local drainages to serve the needs of the surrounding high plains. The map reveals a transition from the mountainous heights toward more accessible terrain in the south and east, marked by several prominent watercourses including Rawhide Creek and Little Rawhide Creek. The presence of a long-distance pipeline and various corral markers across the southern sections suggests a landscape dedicated to ranching and energy transport. This 1980s topographic record captures the area after modern infrastructure was established but before subsequent development altered the hydraulic patterns of these remote drainages.
