Benteen and Senchert: lithic or paralithic contact at depths of 20 to 40 inches. Bavdark, Clayburn, Crystalbutte, Decross, Dranyon, Hagenbarth, and Millerlake: have hues of 7.SYR or yellower in the Bt horizon. Croydon soils have a lithic contact at depths of 40 to 60 inches. Dranbom and Pontuge soils have a xeric moisture regime. GEOGRAPHIC SETTING: Parent material: alluvium and colluvium derived from red sandstone Iandform: mountains, hills, drainageways and fans Slopes: 2 to 45 percent Elevation: 7,000 to 10,000 feet Mean annual temperature: 36 to 42 degrees F Mean annual precipitation: 20 to 26 inches Frost-free period: 30 to 75 days. GEOGRAPffiCALLY ASSOCIATED SOIIS: These are the 13ierro- Leadville and w un series. The I-Terro and Leadville soils Iack a mollic epipedon, have an albic horizon, and have woodland vegetation. The ~chup soils have a layer of peat on the surface and have a water table within 2 feet of the surface.
