1964 Map of Olsen Ranch

About this map

Olsen Ranch sits at the heart of this high-plateau landscape, where the working cattle economy and historic migration routes intersect. The map documents the intricate water management required for ranching in this arid Wyoming environment, featuring several small catchments like Mack Reservoir and Wild Horse Reservoir. Irrigation infrastructure such as the Butler Ditch draws from the New Fork River, which cuts through the northwestern corner of the quadrangle. Historic overland travel is clearly preserved here, with the Emigrant Trail and the Paradise Emigrant Trail crossing the northern terrain. These historic paths are joined by mid-century infrastructure like the Burma Road and the Blue Rim Drift Fence, which follows the contours of the Blue Rim and Ross Ridge to manage livestock movement across the open range.
