1980 Map of Prospect Peak

About this map

Prospect Peak towers over a landscape defined by the drainage systems of the Bridger National Forest in this 1980 survey. The map details a complex network of waterways, including North Horse Creek and South Horse Creek, which carve through the high-elevation terrain of Beaver Ridge. The presence of the Sherman Guard Sta and a nearby Gaging Sta along North Horse Creek suggests a managed wilderness focused on forestry and water resource monitoring. A network of Pack Trails provides the primary means of navigating the high ridges and deep valleys between landmarks like Merna Butte and Haines Flat. This cartography offers an exacting view of the Sublette County backcountry before modern development, capturing the layout of livestock-related features like Pasture Draw and the various springs that supported early 20th-century land use.
