<br />incltes.
<br />These soils are used for grazing, as wildlife habitat,
<br />and for watershed.
<br />Representative profile of Utaline stony loam, 3 to 25
<br />pel•cent slopes, 500 feet south of the Delta-14Iesa County
<br />line, SEl/yNW]/1, sec. 13, T. 4 S., R. 3 E., iu an area of
<br />grass.
<br />A1--0 to 4 inches, pick (7.5YR 7!4) stony loam, brown
<br />(7.SYR 6/4) when moist; moderate, medium,
<br />granular structure, but weak platy structure in
<br />tn~per 2 inches; 30 percent basalt stones and
<br />c~~bbles; slightly calcareous; moderately alkaline;
<br />clear, smooth boundary.

<br />cobbly loam, pink (7.SYR 714) when moist; mas-
<br />sive; slightly hard, friable; i5 percent basalt
<br />cobbles; much secondary calcium carbonate in
<br />finely divided form; moderately alkaline; diffuse,
<br />wavy boundary.

<br />cobbly loam, light brou-n (7.5YR 6/4) when moist;
<br />massive; slightly hard, triable 80 percent basalt
<br />cobbles; much accumulated calcium carbonate but
<br />less than in C2ca horizon; moderately alkaline.
<br />Fragments of basalt make up 35 to 85 ercent, by volume,
<br />the soil. The fine material is loam or clay loam.
<br />UoD Utaline stony loam, 3 to 25 percent elopes.
<br />t soil is gently sloping to steep and is on mesas and
<br />high tet•races. It has the pt•ofile desc]ibed as 1•epresen-
<br />tative of the series.
<br />Included with this soil in mapping are small areas
<br />of Ildefonso soils altd of soils that a]•e about 40 inches
<br />deep to shale.
<br />Runoff is moderate to rapid. The hazard of water
<br />erosion is moderate or high.
<br />This soil is used mainly fot• gt•azing and as wildlife
<br />habitat. Capability unit VIIe-1; Stony Salt Desel•t
<br />I•ange site.
<br />Us--Utaline-Shale outcrop contpler. This complex is
<br />rolling to steep and is on mesa and terrace edges and
<br />breaks. It consists of about 65 percent Utaline stony
<br />loam and about 35 percent Shale outcrop. The Utaline
<br />soil has the profile described as representative of the
<br />sel•ies.
<br />Included with this cmnpler- in mapping are a few
<br />small at•eas of Pel•sayo soils.
<br />Runoff is rapid. The hazard of tvatet• el•osion is high.
<br />This soil is used mainly fot• grazing and as wildlife
<br />habitat. Utaline soil is in capability ]snit VIIe-1 and in
<br />Stony Salt Desert range site; Shale outcrop was not
<br />placed in a capability group or in a range site.
<br />Wet Alluvial Lantl
<br />We-Wet alluvial land. This mapping unit consists
<br />of deep alluvium on stream bottoms, flood plains, and
<br />stvales. This alluvium is highly stratined and is mainly
<br />sandy loam or flue sandy loam, The water table is high
<br />for at least part of the year. Vegetation i•. mostly
<br />rushes, sedges, and grasses. The gron•ing seas~~ ~ ranges
<br />ft•om 50 to 75 clays- Capability unit Vw-1; Mountain
<br />bleadow 1•ange site.
<br />Witt Series
<br />The Witt set•ies consists of deep, well-drained soils.
<br />These soils fm'med in eolian deposits on upland hills
<br />and ridges. The slope is 3 to 12 percent, and elevation
<br />is 6,500 to 7,500 feet. The natural vegetation is mainly
<br />sagebt•ush, rabbitbruslt, tcheatgrass, and bluegrass.
<br />The average annual precipitation is 15 incltes. The
<br />mean annual tempet.•thu•e is 50° F., and the frost-free
<br />seasmt is 100 to 125 clays.
<br />In a representative profile the surface layer is
<br />reddish-brown fine sandy loam about 3 inches thick.
<br />The uppet• pat•t of the subsoil is also reddish-bron•n
<br />fine sandy loam about 3 inches thick. The lotvet• part
<br />of the subsoil is reddish-brown or reddish-yellow clay
<br />loam and pink silty clay loam about 91 inches thick.
<br />The substratum is pinkish-white loam that extends to
<br />bedrock, which is at a depth of about 58 inches.
<br />Witt soils have moderate permeability and a high
<br />available water capacity. They are neutral to a depth
<br />of about 17 inches and moderately alkaline below that.
<br />Roots can penetrate to a depth of 50 to GO inches.
<br />These soils are used for grazing, as tildlife habitat,
<br />and as watershed areas.
