1999 Map of Penrose Peak

About this map

The Coeur d'Alene Mountains dominate this landscape within the Lolo National Forest, where the high ridgelines of the Coeur d'Alene Divide separate the Thompson Falls and Superior Ranger Districts. Notable summits like Penrose Peak and Cherry Peak overlook a dense network of drainages, including Cherry Creek and Rock Creek. This 1999 revision captures a wilderness region largely defined by its natural topography and resource management, with evidence of human activity limited to remote industrial features such as a Gravel Pit and a lone Adit. Small water bodies like Acorn Lake sit high in the drainage basins, while lower elevations are marked by distinct landforms like Greenwood Hill. The boundary between Sanders and Mineral Counties follows the rugged spine of the mountains, illustrating how the physical terrain dictated political and administrative borders in western Montana.
