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.
