About this map

The Continental Divide defines the western edge of this 1995 survey, marking the high boundary between Lewis and Clark and Flathead counties. This landscape is dominated by the massive protected tracts of the Bob Marshall Wilderness and the Sun River Game Preserve, where the headwaters of the South Fork Sun River are fed by numerous tributaries including White Creek and Black Bear Creek.

High-altitude landmarks such as Prairie Reef and Junction Mountain rise above a complex network of drainage basins. The map illustrates the specialized recreational and conservation infrastructure of the mid-1990s, featuring the Lookout Trail and the Scenic Trail which navigate the steep terrain near Hermit Lake and Indian Point. This edition, revised from 1969 aerial photography, provides a detailed record of the forest and wilderness boundaries that have remained largely unchanged for decades.
