About this map

Bob Marshall Wilderness and the Lolo National Forest dominate this 1960s survey of the high Divide country between Powell and Lewis and Clark counties. The landscape is defined by a network of pack trails that provide the only access through the drainage basins of Dwight Creek, Conger Creek, and McCabe Creek. A Lookout Tower sits atop the ridge of East Spread Mountain, overlooking high alpine water bodies like Lake Otatsy and Canyon Lake.

The mapping reveals the intersection of major forest boundaries near Camp Pass and Spread Mountain. Significant elevation markers such as Omar Mountain, Fenn Mountain, and McCabe Mountain frame a terrain where water moves through steep drops like Canyon Falls. This record captures the backcountry as it was maintained for fire surveillance and wilderness recreation before modern digital mapping, preserving the locations of specific mountain points and stream forks.
