About this map

Trilobite Range and the surrounding backcountry of the Flathead National Forest dominate this 1970 survey, capturing a primitive landscape defined by glacial activity and high-altitude water systems. The map details the core of the Bob Marshall Wilderness, where travel was dictated by a complex network of Pack Trails rather than roads. From the heights of Trilobite Peak down to the Spotted Bear River, the topography reveals a drainage system including Argosy, Dolly Varden Creek, and Pentagon Creek.

Remote points of interest such as the Dean Creek Campsite and Dean Falls indicate the era's focus on maintaining access for forest management and wilderness recreation. Significant geological features, including Pot Mountain, Shadow Mountain, and the Trilobite Lakes, provide a clear picture of the high-country terrain before modern satellite mapping, serving as a vital record for those tracking the historical boundaries and naming conventions of this protected Montana wilderness.
