About this map

Henrys Fork snakes through the center of this high-altitude landscape, defining the geographic character of the Targhee National Forest as it flows south toward the Osborne Bridge. The area is geographically unique for its volcanic history, encompassing portions of the Island Park Caldera and Henrys Fork Caldera. Notable water bodies including Golden Lake, Silver Lake, and Swan Lake are scattered across the terrain, reflecting the complex drainage patterns of the Continental Divide.

Settlement is concentrated at Last Chance near the northern boundary, where the Mesa Falls Scenic Byway provides access to the region. The map documents various forest access routes like Wood Road 16 and specialized infrastructure such as the REA Powerline and the Osborne Pit. Local landmarks like Osborne Butte and Thurmon Ridge stand as prominent features for navigators and historians tracing the early development of this portion of Fremont County.
