About this map

Boars Tusk rises as a prominent landmark in this 1950s survey of the high desert landscape north of Rock Springs. The map documents a period of early resource extraction and ranching across the North Baxter Basin, where scattered Oil Wells, a Gas Well, and the Chilton Mine sit alongside historic homestead sites. The geography is defined by the Continental Divide and dramatic volcanic and sedimentary formations including North Table Mtn, South Table Mtn, and the expansive Sand Dunes.

Evidence of early Wyoming settlement and passage is visible in the network of Jeep Trails and the Winton Cutoff Road. Water remains the central concern for the era's land use, noted by the Fifteenmile Knoll Reservoir and the locations of the Lewis Ranch, Houghton Ranch, and Cookston Ranch. These features illustrate how the high plains were managed before modern infrastructure, marking a specific chapter in the state's transition from open range to industrial development.
