Landscape Characteristics:

Glaciated fault block mountains that formed from complexly folded and faulted sedimentary and igneous rocks. Elevations range from 4000 to 10200 feet. Drainage density is moderate to high. Lakes are common in cirque basins.

Climate:

Mean annual precipitation ranges from 11 to 50 inches, about 55 percent falling as snow. The soil temperature and moisture regimes are cryic and typic ustic.

Potential Vegetation:

Douglas-fir forest/Foothills prairie

Relationships of Dominant Map Unit Components:

Landform Geology Soil Taxa
Ridges/cirquelands Mixed sedimentary/metasedimentary/granite Cryochrepts/Cryorthents
Mountainsides/benches Mixed sedimentary/metasedimentary/volcanic Cryoborolls/Cryoboralfs/Cryochrepts

Disturbance and Land Use:

The primary natural disturbance is fire. Land use is predominantly timber harvest, grazing, mining, and suburban development.
