1958 Map of Horseshoe Peak

About this map

Flathead National Forest encompasses the entirety of this 1958 survey, capturing a high-altitude wilderness defined by the Horseshoe Peak and Trinity Mountain massifs. The landscape is characterized by a network of drainage basins, where the headwaters of Castle Creek, Dryad Creek, and Spy Creek carve deep valleys through the mountain ranges. Higher elevations are marked by isolated alpine features like Flotilla Lake and Bradley Lake, which sit below the ridgelines of Hematite Peak and Twin Mountain. This area is navigated almost exclusively by a system of Pack Trails, emphasizing its isolation and lack of vehicular infrastructure during the late 1950s. The presence of Condor Peak and Spy Mountain further illustrates the complex topographic profile of this interior Montana wilderness, used primarily for resource management and backcountry transit.
