Undistur.~~ed Soil Classification A soil survey was o~ipleted in Jackson Canty in 1973. TWo soil types were mapped on and arotud the Baag Mine permit area, the ayorthent family an the steeper slopes aryl the Fluetsch series aa~ shallower slopes, specifically the Fluetsctr~Piagos association (USDA-S6, ]973 j . The following desai.ptions are frcmm the Soil Omiservation Service. Cryorthents includes a variety of shallow soils that differ in depth, color texture, reaction, and mi noral ogy, They ate on steep terrace breaks and uplarrl ridges between elevations of 7,980 and 9,200 feet. Slopes are 15 to 70 percerst. The native vegetation is mainly bl»P*~~+ wheatgrass, needle-ard-thread, Indian rioegrass, wi.rrterfat, law rabbitbrush, and fringed sage. These soils ate generally less than 20 inches deep over soft shale or f sandstone and have little or no horizon development. In some of the areas mapped as Cryorthents (steep), the soils ate deep and cobble-filled or have various depths of cobbly material over shale. In some areas on tenaoes, side slopes, aryl breaks, the wobbly wpsi~urden is deeper at the upper part of the slope. Available water capacity is generally low. The_Se soils are on unfavorable exposure, and much of the moisture is removed by strung winds. F3noff is rapid. The hazards of soil blowing ar,d water erosion are severe. The Fluetsch series ooa~sists of deep, well drained soils that formed in calcareats alluvium Prtm sandstone atd sandy shale. They are on old alluvial fans, old hick terxaoes, arrl valley sides between elevations of 8,000 and 9,000 feet. Slopes are 2 to 15 pervert. The native vegetation is mainly pine needlegrass, J~irmra~a, muttcuigra_ts, streaIDbarilc Wheatgrass, bluebunch wheatgrass,
