<br />SOIL SIIRVEY
<br />Runoff is rapid on this soil. The erosion hazard is high.
<br />This soil takes in water slowly. It is difficult to work.
<br />About half of the acreage is used for irrigated crops,
<br />and the rest for dry.]and crops. (Capability units IPe-1,

<br />J.uget_Sezies
<br />The Juget series is mnde up of shallow, somewhat ex-
<br />cessively drained soils. These soils formed on mountain
<br />slopes and ridges in sandy residuum weathered from
<br />granite. Slopes are 9 to 55 percent. Elevations are fi,300 to
<br />5,200 feet. At lower elevations the native vegetation is
<br />mainly ponderosa pine, and at higher elevations it is
<br />Engelmann spruce and Douglas-fir with an understory of
<br />grass. Annual precipitation is 18 to 24 inches. ivfean annual
<br />air temperature is 43° to 46° F., and the frost-free season
<br />is about 80 to 120 days.
<br />In a representative profile the surface layer, about 6
<br />inches thick, is dark-gray very gravelly sandy loam. The
<br />underlying material, about 5 inches thick, is brown very
<br />gravelly ]oamp sand. IInderlping this layer is granite.
<br />Soil reaction is slightly acid.
<br />Juget soils have rapid permeability. Available water
<br />capacity for the profile is ]ow. Roots can penetrate to a
<br />de th of less than 20 inches.
<br />These soils are used mainly for grazing, although some
<br />Wrens with scattered trees are used for recreation, for-
<br />estry, and homesites. The grass cover must be maintained
<br />to help prevent erosion.

<br />(JrFI.-This complex is made up of about 50'percent7uget
<br />very gravelly sandy loam and about 30 percent Rock
<br />outcrop. This complex is in the western part of the Area.
<br />The profile of the .Iuget soil in this complex is the one
<br />described as representative of the Juget series.
<br />Incllidecl with this complex in mapping are small areas
<br />of Peyton soils near drainageways and a few small areas
<br />of Aliens Park soils. These included soils make up about
<br />20 percent of each mapped area.
<br />Runoff is rapid on this complex. The erosion hazard is
<br />high. Juget soils take in water readily, but they retain
<br />only limited amounts for plant use because of their shal-
<br />low depth to bedrock.
<br />None of this complex is suitable for cultivation. It is
<br />in grass and scattered terees and slu•ubs: In the past, it
<br />was used far grazing livestock and for forestry, but now
<br />many areas are use3 for homesites, recreational purposes,
<br />and wildlife habitat. (Capability unit VIIs-1, nonirri-

<br />Kim Series
<br />The Kitn series is made up of deep, well-drained soils.
<br />These soils formed on terraces in calcareous, loamy allu-
<br />vium. Slopes are 0 to 3 percent. Elevations are 4,900 to
<br />5,500 feet- Tha native vegetation was mainly short grass-
<br />es. Annual precipitation is 12 to 18 inches. Mean annual
<br />air temperature is 48° to 52° F., and the frost-free seaso^
<br />is about 140 to 155 days.
<br />In a representative profile the surface layer, about 11
<br />inches deep, is strongly calcareous, pale-brown clay loam.
<br />The underlying material is strongly calcareous, pale-
<br />bron-n and brown sandy clay loam and clay loam that
<br />reaches to a depth of 60 inches or more. Some soft lime
<br />segregations are in the upper part of this material. In the
<br />surface layer, soil reaotion is mildly alkaline, and in the
<br />underlying material, it is moderately alkaline.
<br />Kim soils have moderate permeability. Available water
<br />capacity for the profile is high. Roots can penetrate to a
<br />depth of 60 inches or more.
<br />These soils are used mainly for irrigated crops and are
<br />productive if well managed.

<br />Hutch Series
<br />The Kutch series is mnde up of moderately deep, well-
<br />drained soils. These soils formed on uplands and valley
<br />sides in clayey residuum weathered from sedimentary
<br />rock. Slopes are 3 to 9 percent. Elevations are 4,900 to
<br />5,500 feet. The notice cegetntion is mainly short and mid

<br />free season is about 140 to 155 days.
