2024 Map of Keystone Peak

About this map

Clark Fork carves through the northern reaches of this Mineral County landscape, defining the topography of Donlan Flats and the nearby settlement of Donlan. The terrain climbs sharply away from the river into the Coeur d'Alene Mountains, where the Lolo National Forest encompasses a network of steep drainages like Sloway Gulch and Brian Gulch. The southern portion of the map is anchored by the historic settlement of Keystone, situated near the confluence of several gulches beneath the prominence of Keystone Peak. This area's geography is defined by its transit routes and water sources, from the River Trl following the riverbanks to the high-elevation Donlan Saddle Trl. The map illustrates a classic Montana mountain landscape where early 21st-century infrastructure like Pardee Creek Rd navigates the narrow valleys between ridges such as Bald Hill.
