1938 Map of Mt Bonneville

About this map

Mt Bonneville and the high peaks of the Wind River Range define this high-altitude landscape along the border of Fremont and Sublette counties. Surveyed in the late 1930s, the map documents a wilderness primarily accessible by a network of named trails, connecting isolated outposts such as the John Day Cabin and Cow Camp. The Continental Divide winds through the center of the sheet, separating the headwaters of the Wind River and the Little Wind River to the east from the extensive lake basins of the west. Glacial features are prominent, including the Bonneville Basin and dozens of alpine lakes like Lake Solitude, Middle Fork Lake, and Raft Lake. This survey provides a record of the Shoshone National Forest prior to modern administrative changes, noting backcountry infrastructure like the South Fork Guard Sta and a dam on Silver Lake.
