About this map

Pinnacle sits at a critical transit point where the Middle Fork Flathead River carves a canyon between the high peaks of Glacier National Park and the Flathead National Forest. This 1963-1964 survey documents a landscape defined by movement through the Stevens Pass corridor, following the route of the Theodore Roosevelt Highway and the railroad engineering required to navigate this terrain, including Tunnel No 2 and Tunnel No 3.

The map reveals a transition into the high backcountry of the Great Bear Wilderness, where family-named landmarks like Mount Liebig and the ice of Grant Glacier overlook the drainage basins of Paola Creek and Dickey Creek. The intricate network of pack trails, such as the Pack Trail near Marion Lake, illustrates the historical reliance on non-motorized access to these alpine reaches before the establishment of modern wilderness boundaries.
