Soils of the Douglas-fir Forest are shallow and droughty, usually • less than 20 inches to hard bedrock with a dark brown surface gravelly loam layer. The representative profile for this unit is a member of the coarse loamy mixed family of Typic Cryoborolls. Typically, these soils have very dark grayish brown (lOYR 3/2) sandy loam surface layers to 11 inches. The substratum is dark grayish brown (lOYR 4/3) very gravelly and cobbly sandy loam to 25 inches. Hard shale bedrock occurs at 25 inches. Phyto-Edaphic Unit 4 - Low Elevation Pinyon-Juniper/Shallow Very Gravelly Loams (Juniper Woodland in the Colony permit areas) The Pinyon-Juniper Woodland type occurs on very gravelly and cobbly shallow soils over hard bedrock. Rock outcrops are common but occupy less than 30 percent of the area. Bare ground usually covers 60 to 90 percent of the area. Soils are less than 20 inches to hard bedrock, but usually are less than 10 inches deep. • The representative soil profile for this unit is a member of the loamy-skeletal mixed frigid calcereous family of Lithic Ustic Torriorthents. Typically, these soils have brown and pale brown, very gravelly sandy loam surface layers to 10 inches. Hard shale bedrock occurs at 16 inches. Phyto.-Edaphic Unit 10 - High Elevation Big Sagebrush/Dark Brown Loams (High Elevation Big Sagebrush in the Colony permit area) Soils of the Bigh Elevation Big Sagebrush Shrubland type are dark brown loamy deeper than 20 inches to bedrock, cobbles, or stones. Two major soils occur in a complex pattern. The domi- nant soil (658 of the area) has about 14 inches of very dark brown loam soil over about 20 inches of gravelly material over fractured bedrock. The second soil is very dark brown and more than 16 inches thick without the gravelly layer, and bedrock • does not occur until .40 to 60 inches depth. J-12
