About this map

Lolo National Forest covers much of this high-elevation landscape along the border of Sanders and Mineral Counties. Defined by the Coeur d'Alene Mountains, the area is anchored by prominent summits like Penrose Peak and Cherry Peak. The topography is etched by a complex drainage system including Cherry Creek and Flat Rock Creek, which carve through features with evocative local names such as Happy Hollow and Cedar Tangle. The presence of Acorn Lake near Eddy Creek provides a rare point of still water amidst the steep ridgelines.

Logistics in this wilderness are dictated by the terrain, with Twelve Mile Rd following the lower elevations while W Camels Hump and various forest tracks skirt the C C Divide. The map highlights the intersection of natural geography and administrative boundaries, tracing the Sanders Co line across Greenwood Hill. For those studying Western Montana land use, the mix of national forest land and named ridges like Flat Rock Ridge illustrates the persistent character of this remote mountain range.
