1968 Map of Downs Mountain

USGS Topo · Published 1985

About this map

Continental Divide crests through this high alpine landscape, defining the boundary between Fremont and Sublette counties. The 1968 field survey documents an era of significant glaciation across the Wind River Range, featuring the massive Continental Glacier and Downs Glacier, alongside smaller ice bodies like Connie Glacier and Grasshopper Gl. This terrain is characterized by expansive high plateaus such as Ram Flat and Goat Flat, which stand in contrast to the jagged summits of Downs Mountain and Yukon Peak. The map captures the hydrological complexity of the area, where the Roaring Fork and Clear Creek begin their descent. Within the Bridger Wilderness and Shoshone National Forest, numerous remote alpine basins hold waters like Mile Long Lake, Upper Ross Lake, and Bear Lake, reflecting a wilderness state before modern climate shifts impacted these perennial ice fields.
