2014 Map of Pinnacle

About this map

The Middle Fork Flathead River carves a critical corridor through the mountainous terrain of the Flathead Range, defining the boundary between Glacier National Park and the Flathead National Forest. This 2014 survey documents the rugged geography near the settlement of Pinnacle, where transportation infrastructure must navigate extreme relief via John F Stevens Canyon. Notable engineered features include Tunnel Number 2 and Tunnel Number 3, which facilitate transit through the narrow pass alongside Us HWY 2. High-altitude water bodies such as Marion Lake, Almeda Lake, and Dickey Lake are scattered across the slopes of Essex Mtn and Mt Liebig. The map also captures the path of Theodore Roosevelt Pass, illustrating the continued importance of this mountain crossing for both modern highway and rail traffic.
