1964 Map of Olsen Ranch

About this map

The New Fork River winds through the northern reaches of this Sublette County landscape, flanked by the Bertram Ditch and Butler Ditch irrigation networks. This mid-1960s terrain is defined by its ranching infrastructure and historic passage, most notably the path of the Emigrant Trail cutting across the northern sections. Central to the local operations is the Olsen Ranch, positioned near the junction of drainage systems and the long Blue Rim Drift Fence that follows the edge of the Blue Rim plateau. The map records a water-scarce environment managed through man-made features like the Granite Reservoir and Wild Horse Reservoir, alongside natural features such as Ross Ridge and the broad North Alkali Draw. The presence of the Burma Road underscores the development of backcountry access across the high desert flats of The Mesa.
