About this map

Hungry Horse Reservoir dominates the western portion of this 1981 survey, where the dammed waters of the South Fork Flathead River fill the deep valleys between Emery Ridge and Pioneer Ridge. The landscape is a study in transport corridors through difficult terrain, most notably along the Middle Fork Flathead River where the Theodore Roosevelt Highway and the Burlington Northern railroad track through the John F Stevens Canyon. This route connects small mountain settlements like Nyack, Paola, Essex, and Walton as it climbs toward the Continental Divide.

Conservation and wilderness boundaries define the region, with the map showing the intersection of Glacier National Park, Flathead National Forest, and the Bob Marshall Wilderness. To the east, the terrain opens slightly near East Glacier Park and the Two Medicine Lake area, marking the transition from high peaks like Mount Saint Nicholas and Great Northern Mountain toward the rolling country of the Blackfeet reservation boundary. The presence of several mountain lookouts and remote railroad sidings illustrates the region's historical reliance on fire monitoring and heavy rail logistics.
