1949 Map of Pat O'Hara Mountain

About this map

Pat O'Hara Mountain and the surrounding high country of Park County are depicted here in a detailed postwar survey. The landscape is defined by the sharp descent from peaks like Pat O'Hara Peak down into the Pat O'Hara Basin, where a network of seasonal and permanent watercourses like Dry Fork Pat O'Hara Creek and Oxyoke Canyon Creek drain the slopes. The map captures a moment when traditional land use is visible through family-named holdings such as Cles Ranch, Rhodes Ranch, and Four Bear Ranch. Dramatic geological features, including the Rattlesnake Palisades and the Natural Corral, highlight the area's complex topography. Evidence of early tourism and wilderness access appears via Tourist Cabins and several remote structures like Pearson Cabin and Robbers Roost Cabin, while the presence of Buffalo Bill Reservoir in the southeast corner marks the impact of regional water management projects in the Missouri River Basin.
