M M ~~ Intermingled with the Catamount soil; granite outcrop in the form of bouldery knobs and as small areas where just the bedrock surface is exposed On toe slopes; deep soils with dark surface layers 6 to 24 inches thick similar Inclusions On north-facing side slopes; moderately deep soils that lack the clay loam or sandy clay loam subsoil of the Guffey soil Shallow soils commonly have a fine-earth fraction texture of loamy coarse sand or coarse sand below depths of about 12 inches On lower south-facing side slopes; shallow soils with dark surface layers 5 to 8 inches thick Major IIses woodland, wildlife habitat, urban development Major Management Factors Soil-related factors: Catamount soil=shallow depths to bedrock, rapid permeability, Low fertility, very low available water capacity, steepness of slope, high content of rock fragments; Guffey soilanoderate depths to bedrock, very law available water capacity, steepness of slope, high content of rock fragments Climatic factors: Mean annual precipitation=l7 to 20 inches Mean annual air temperature=38 to 42 degrees F frost-free period=50 to 80 days Elevation=9,000 to 9,800 feet Woodland (Catamount soil) Major tree species: Open stand of Douglas fir Minor tree species: Linter pine, ponderosa pine (ponderosa pine is dominant on same south-facing side slopes north of U.S. Highway 24) Dominant understory vegetation: Kinnickkinnick, common juniper, prairie j uneg rass, Arizona fescue, Parry oatg rass Mean site index for Douglas fir: 48 Condition of unsurfaced roads and skid trails when wet: Firm Hazard of erosion in cut-and-fill and other disturbed areas: Very high Management concerns: The use of tree spades for planting seedlings or removing transplants is difficult because of the high content of small gravel. This unit is best suited for recrea cion, wildlife habitat, and watershed. The soils are susceptible to sheet and rill erosion where runoff is concentrated or where the plant cover is disturbed. Woodland (Guffey soil) Major tree species: Douglas fir Minor tree species: Engelmann spruce, ponderosa pine, quaking aspen Dominant understory vegetation: Kinni ckkinnick, common juniper, Oregon grape, sedges, prairie junegrass, Arizona fescue Mean site index for Douglas fir: 52 Condition of unsurfaced roads and skid trails when wet: Firm Hazard of erosion in cut-and-fill and other disturbed areas: Yery high fleJvl~l{{.G LVaDl JU+7JL(.! l~ t,~.O~Yfui.
