Grayrocks Reservoir dominates the southeastern corner of this map, reflecting the mid-twentieth century water management strategies that shaped the arid high plains of Wyoming. This 2021 survey documents the topography of the Laramie River drainage area, where seasonal watercourses like Big Sand Draw and local water sources such as Box Springs have historically dictated the patterns of ranching and settlement. The landscape transitions from the open plains of Bettelyoun Flats to the more varied terrain around Warm Springs Canyon, where the presence of Warm Springs indicates the geothermal activity characteristic of this region.
