1951 Map of Lone Mountain

About this map

High-altitude desert terrain and isolated summits define this 1951 survey of the Missouri River Basin development area. Lone Mountain and Countryman Peak dominate the landscape, providing fixed points for surveyors navigating the complex topography of the Wyoming backcountry. The water network is sparse, centered on the drainage of Sage Hen Creek and the critical watering point at Sage Hen Springs in the northern portion of the quadrangle. A network of unimproved roads and trails connects distinct natural landforms like Vice Pocket and Beef Gap, illustrating how early ranching and mapping parties traversed this part of Natrona County before more modern infrastructure arrived. The map reflects a mid-century effort to document the remote interiors of the Western states for federal land and water management programs.
