About this map

Helena National Forest and Lolo National Forest converge in this high-altitude wilderness along the border of Lewis and Clark and Powell counties. The landscape is defined by the headwaters of the Blackfoot River, where the North Fork and East Fork meet. Prominent summits like Olson Peak, Galusha Peak, and Bugle Mountain overlook a complex network of drainages, including Theodore Creek and Mineral Creek.

A system of pack trails, such as the Main Line Trail, provides the only access through this roadless backcountry. The presence of Twin Lakes and Meadow Lake tucked into the drainages of Pony Creek and Meadow Creek highlights the glaciated character of the terrain. This map serves as a primary record of the trail routes and hydrological sources within these protected forest lands prior to modern aerial inspection updates.
