About this map

Casper serves as the industrial and transportation hub for this mid-century central Wyoming landscape, anchored by an oil refinery and the Casper Air Terminal. The North Platte River system is heavily managed for water storage and power, evidenced by the expansive Pathfinder Reservoir, Alcova Reservoir, and Seminoe Reservoir. These waters contrast with the surrounding high-desert terrain of the Great Divide Basin and the Granite Mountains.

Resource extraction is the primary economic driver throughout the region, ranging from the Uranium Mill and Lucky Mac Camp in the west to the Poison Spider Oil Field and scattered coal mines. Small post offices and ranching headquarters like Bairoil (P.O.), Ervay, and Hiland dot the vast distances between mountain ranges such as the Rattlesnake Range and Ferris Mountains, illustrating the isolated character of Wyoming's rural settlements during this era of development.
