1964 Map of Pinnacle

About this map

The Middle Fork Flathead River carves a path through the northeastern corner of this 1964 survey, defining the boundary between Glacier National Park and the Flathead National Forest. Along the river’s western bank, the Great Northern Railway and the Theodore Roosevelt Highway navigate the steep terrain near the settlement of Pinnacle. This corridor was critical for transcontinental travel, evidenced by engineering features like Tunnel No 2 and Tunnel No 3 that pierce the mountain ridges.
