About this map

Flathead National Forest defines this high-elevation wilderness in Montana, where the headwaters of the Spotted Bear River and its tributaries carve deep through the Trilobite Range. The landscape is dominated by a series of prominent peaks and ridgelines, including Pentagon Mtn, Pot Mtn, and the namesake Trilobite Peak. Water is a defining element of the terrain, with features like Dean Falls and high-mountain basins holding Shadow Lake and Pot Lake.

Transport through this backcountry relies on a network of historic trail systems rather than roads. The Dolly Varden-Pentagon and Chair Mtn. Trilobites trails navigate the complex topography, connecting remote points like Switchback Pass and Roaring Argosy. This 2020 survey provides a precise view of the drainage patterns for Dean Creek and Pentagon Cr, serving as a vital reference for understanding the hydrological and geological layout of this protected area.
