1964 Map of Pinnacle

About this map

The Great Northern railroad corridor carves a vital path through this high-altitude landscape, following the course of John F Stevens Canyon and the Middle Fork Flathead River. This 1964 survey captures the infrastructure required for such a crossing, including Tunnel No 2 and Tunnel No 3, alongside the Theodore Roosevelt Highway. The small settlement of Pinnacle sits at the northern edge of the sheet, serving as a landmark within the Flathead National Forest and adjacent to the Glacier National Park boundary.
