About this map

The Continental Divide serpentines across this high-altitude landscape where Sublette and Fremont counties meet. This survey captures a massive alpine watershed characterized by glacial activity, including the Hooker Glacier tucked beneath Tower Peak and Mount Hooker. The drainage systems of the East Fork River and Boulder Creek are defined by high-country basins and chains of glacial lakes like the Bonneville Lakes and Grave Lake.

Human presence is marked by a network of established wilderness routes, including the Fremont Trail and Highline Trail, which navigate the steep terrain of the Bridger Wilderness. The map also delineates the western boundary of the Wind River Indian Reservation as it crosses Pilot Knob. Significant peaks like Mount Bonneville and Mount Washakie serve as the primary landmarks for navigators crossing the high passes at Hailey Pass and Washakie Pass.
