About this map

Lolo National Forest encompasses the entirety of this high-elevation landscape, where the Coeur d'Alene Mountains form a significant physical barrier. The administrative boundary between Sanders County and Mineral County follows the prominent C C Divide, a ridge system that dictates the drainage patterns for numerous mountain streams. Significant summits include Penrose Peak and Cherry Peak, the latter feeding Cherry Creek and its eastern fork. Small alpine features like Acorn Lake sit tucked below the ridges, providing water sources alongside Breen Spr.

The hydrography of the region is defined by deep drainages such as Buzzard Gulch and the winding paths of Twelvemile Creek and Flat Rock Creek. Human imprint is minimal, represented largely by the Natl Forest Develop Road 352 Rd, which provides access through the heavily timbered terrain. This survey illustrates the intricate watershed networks of the Northern Rockies, where steep slopes transition into named valleys like Greenwood Hill.
