1961 Map of Antelope Reservoir

About this map

Antelope Reservoir and the drainage patterns of the Wyoming high desert define this portion of Sweetwater County. The map documents a landscape primarily shaped by seasonal water management and resource extraction, with ephemeral water bodies like Little Osborne Lake and Eagles Nest Draw Reservoir No 1 providing critical water sources in an otherwise arid environment. The presence of several prospects in the northeast suggests early-stage mineral exploration during the mid-20th century. The terrain is marked by significant topographical features such as Osborne Draw and Eagles Nest Draw, which dictate the local hydrology. This 1961 record, later updated in the early 1980s, captures the sparse ranching and mining infrastructure that characterized this remote section of the state during a period of expanding land use.
