Pagoda and Hesperus soils have mollic <br />epipecons.'which are 16 or more inches thick. Herm soils are <br />noncalc~areous... Iles and Campspass soils co not have moilic epipedons. <br />DRAINAGE AND_PERMEABiLITY:. Well grained; rapid runoff; slow <br />permeability. <br />USE AND VEGETATION: These soils are used mainly for rangeland. Some <br />are used for dryland wheat and alfalfa. Principal native vegei:ation is <br />.mountain big sageorush, serviceberry, oromes, neeclegrasses, and <br />whea.tgrasses as well as ponaerosa pine anc pinyon and juniper ..roodland. <br />DISTRIBUTIGN AND EXTENT: Western Colorado and possibly adjacent parts <br />of Wyorning.and Utah. The series is of moderate extent. <br />SERIES ESTABLISHED: Moffat County (Moffat County Area, Colorado, 1991. <br />REMARKS: .The name Yorapos is taken from Morapos Creek which is near th;. <br />type location. Climatic conditions are close to r"fitting that or the <br />xeric mois'tu.re regime. Snow cover occurs in OctcSer before the moisture <br />control'section oecomes moister~ed in all parts; hence it nas no <br />opportunity to be moist in all parts for 3 of the ti months after the <br />winter solstice. Snow melt occurs in mid-April to mid-play anG moistens <br />\. t . <br />the..control. s.ec ion env below. Increased evapotransporation cries out <br />~~~~the c~ontr'ol~section by mid-July. Summer precipitation comes as <br />irregu'Iar~showers which are not sufficient to moisten the soil sown <br />ti7e top.of. th'e control section. As evapotransporation decreases in lat. <br />September,. the showers moisten the soil down into the top part of the <br />moisture control-section. <br />Diagnos.t,ic 'ho.rizons inciuae the moilic <br />i:nch.es;;;.jan:d.'th.e argillic horizon - the <br />~. <br />°~,';C - <br />epipedon, the zone from 0 to 9 <br />zone from 'S to, 23 inches.
