It formed in mixed colluvium and residuum. <br />F.levatton is 7,000 to 8,500 feet. The average annual precipi[a[Lon is IFS to <br />25 Inches, the average annual air temperature is 37 to 40 degrees F, and ilia <br />Eros[-free season is 40 to 65 days. <br />Typically, tl~e surface layer Ls very dark grayish brown to brown lu;~m <br />about 26 inches thick. The upper part of the subsoil !s yellowish brawn <br />clay loam about 12 inches thick. The lower part of [lie subsoil to a d~l~tli <br />of b!1 inches or more is yellowish brown and light yellowish brown silty clay <br />loam. <br />Included in this unit are small areas of (:ou[1s tine sandy lu~im, <br />(;oclie[opa loam and Wlnevada loam. <br />. Permeability of this Rout[ soil is very slow. Effective routing depth <br /> is 60 inches or more. Available water capacity is high. Runoff Is medium, <br /> and the hazard of water erosion Ss high. <br />This unit is used for livestock grazing and wildlife liabi[a[. <br />The potential plant community on this unit is mainly Gainbel oak, <br />Saskatoon serviceberry, mountain snowberry, elk sedge, Kentucky bluegrass, <br />nodding bromegrass, slender whea[grass, and mountain brome. The averal;e <br />annual production of sit-dry vegetation is 2,500 pounds. <br />If the range condition deteriorates, less preferred forage planes <br />increase. In poor condition, undesirable plants are dominant. Therefore, <br />grazing should be managed so that the desired balance of species is <br />maintained in [he plan[ community. <br />Management practices suitable for use on this unit are proper grazing; <br />use and a planned grazing system. <br />9-52 Revised 03/26/57 <br />
