About this map

Union Peak stands as a prominent landmark in this high-altitude landscape where the Continental Divide weaves across the Wind River Range. The 1991 survey reveals a complex network of glacial lakes and drainage basins shared between the Shoshone National Forest, Teton National Forest, and Bridger National Forest. The presence of the Fitzpatrick Wilderness and Bridger Wilderness indicates a strictly managed alpine environment where historical access was primarily defined by foot and pack animal.

Traces of early transit and resource extraction appear at Gravel Pit and along the Seven Lakes Trail, while the remote Ryan Park sits in the southwestern reaches of the quadrangle. The map captures the meeting point of Fremont, Sublette, and Teton counties, marked by topographic extremes like Three Waters Mountain and the deep basin of Granite Lake. Remote mountain passes such as Gunsight Pass along Pinon Ridge illustrate the challenging routes once used to traverse these summits before modern conservation designations.
