1968 Map of Downs Mountain

About this map

The Continental Divide carves through the high Wind River Range in this late 1960s survey, separating the high-altitude terrain of Fremont and Sublette counties. This alpine landscape is defined by its massive ice fields, most notably the sprawling Continental Glacier and the Downs Glacier, which feed the headwaters of the Downs Fork. The map documents the overlap of the Shoshone National Forest and Bridger National Forest, including the protected Bridger Wilderness. Unlike lower-elevation maps of the era, the terrain here is largely devoid of roads or settlements, focusing instead on geological landmarks like Downs Mountain and Shale Mountain. High-altitude basins like Bear Basin and uniquely shaped water bodies, such as Mile Long Lake and Upper Ross Lake, highlight the glacial carving of the granite plateau.
