About this map

The Bob Marshall Wilderness and Lolo National Forest dominate this high-elevation landscape, where the continental divide follows the boundary between Powell and Lewis and Clark counties. The terrain is characterized by a series of steep drainages and prominent peaks, including Omar Mountain and Fern Mountain. A significant network of pack trails serves as the primary infrastructure through the wilderness, connecting remote water bodies such as Canyon Lake, Lake Otatsy, and Camp Lake Creek.

Spread Mountain and East Spread Mountain anchor the southern half of the sheet, with a Lookout Tower positioned at the summit of the former to monitor the surrounding timberlands. The hydrological pattern is defined by radiating creek systems, including Canyon Creek, McCabe Creek, and the East Fork Spread Creek. The reliance on pack trails rather than roads emphasizes the area's designation as a protected primitive landscape during the late 1960s.
