<br />More than half of the acreage is cultivated and
<br />is used to grow small grain, mainly wheat and some
<br />sorghum for hay. The rest of the acreage is in
<br />native pasture and is cued for grazing livestock.

<br />Newlin Series
<br />The Newlin series consists of well-drained soils.
<br />These soils formed in alluvial soil materials
<br />derived from mixed sources and are moderately deep
<br />over unconformable very gravelly sand. They are
<br />rolling to moderately steep soils on uplands and
<br />side slopes. Slopes are 8 to 30 percent. The
<br />vegetation is mainly mid and tall grasses, but in
<br />places mountain-mahogany, Gambel oak, and squawbush
<br />are present. Elevations are 5,500 to 6,600 feet.
<br />Annual precipitation is 15 to 19 inches. Mean annu-
<br />al soil temperature is 49° to S1° F., and the frost-
<br />free season is 120 to 135 days.
<br />In a representative profile the surface layer is
<br />dark grayish-brown gravelly sandy loam about 8
<br />inches thick. The subsoil, about 14 inches thick,
<br />is brown and light-brown gravelly sandy clay loam
<br />and gravelly sandy loam. The underlying material
<br />is brownish-yellow very gravelly sand that extends
<br />to a depth of 60 inches or more.
<br />Newlin soils have moderate permeability. Avail~~
<br />able water capacity is low. Plants penetrate to a
<br />depth of 60 inches or more.
<br />Most areas of Newlin soils are in native grasses
<br />and are used for grazing livestock and for wildlife
<br />habitat. Where gravel beds are thick, these soils
<br />are sources of gravel for construction.
<br />Representative profile of a Newlin gravelly sandy
<br />loam, 400 feet east and 400 feet south of the north-
<br />west corner of sec. 30, T. 7 S., R. 67 W.:
<br />Al--0 to 8 inches, dark grayish-brown (lOYR 4/2)
<br />gravelly sandy loam, very dark brown (lOYR
<br />2/2) when moist; moderate, medium, granular
<br />structure; soft, very friable; 25 percent
<br />gravel; neutral (pH 6.8); clear, smooth
<br />boundary.
<br />82t--8 to 17 inches, brown (7.SYR 3/4) gravelly
<br />sandy clay loam, dark brown (7.SYR 4/4) when
<br />moist; moderate, coarse, prismatic structure
<br />parting to moderate, medium, sub angular
<br />blocky; very hard, friable; many, thin, patchy
<br />clay films on horizontal and vertical faces
<br />of peds; 25 percent gravel; neutral (pH 6.8);
<br />clear, smooth boundary.
<br />B3--17 to 22 inches, light-brown (7. SYR 6/4) grav-
<br />elly sandy loam, brown (7.SYR 5/4) when
<br />moist; weak, coarse, prismatic structure;
<br />hard, friable; few patchy clay filnLS on faces
<br />of peds; 35 percent gravel; neutral (pH 6.8);
<br />clear, wavy boundary.
<br />IIC--22 to 60 inches, brownish-yellow (lOYR 6/6)
<br />very gravelly sand, yellowish brown (lOYR 6/6)
<br />when moist; single grain; loose when dry and
<br />moist; 50 percent gravel; neutral (pN 7.0).
<br />
<br />The A horizon ranges from 3 to 10 inches in
<br />thickness and from gravelly sandy loam to gravelly
<br />loamy sand in texture. The B2t horizon ranges from
<br />6 to 24 inches in thickness and from gravelly sandy
<br />clay loam to gravelly clay loam in texture. Gravel
<br />content of the B horizon ranges from 15 to 50 per-
<br />cent, but the average is less than 35 percent, Sand
<br />and gravel are at a depth of 20 to 40 inches. Gravel
<br />content of the C horizon ranges from 35 to 60 per-
<br />cent. In places sandstone or shale is below a depth
<br />of 40 inches.
<br />Newlin ravell sand loam, 8 to 30 ercent
<br />slopes NeE .--This rolling to steep soil is on up-
<br />lands and terrace side slopes in the northern part
<br />of the area. Most mapped areas are more than 100
<br />acres in size. A few small areas are next to stream
<br />channels.
<br />Included with this soil in mapping are small
<br />areaz of Bresser sandy loam, 3 to 9 percent slopes,
<br />that are on the lower part of slopes adjacent to
<br />drainageways and that make up about 20 percent of
<br />each mapped area. Also included are areas of Staple-
<br />ton loamy sand, 6 to 30 percent slopes, that are on
<br />knobs and points seldom exceeding 2 acres in size,
<br />and small areas of Satanta loam on the highest,
<br />smoothest part of the landscape.
<br />Runoff is medium. The erosion hazard is slight
<br />to moderate.
<br />Most areas of this soil are used for grazing
<br />livestock. Wildlife habitat is important in places.
<br />(Capability unit VIe-2; Gravelly Foothill range
<br />site)
<br />Newlin-Satanta complex, 5 to 20 percent slopes
<br />(NsE).--This complex is an intricate mixture of
<br />about 50 percent Newlin soils and about 30 percent
<br />Satanta soils. In most places Newlin soils are on
<br />knobs and side slopes leading down to drainageways
<br />and Satanta soils are at higher elevations than
<br />Newlin soils.
<br />The Newlin soil has a profile similar to that
<br />described as representative of the series.
<br />The Satanta soil has a profile similar to the one
<br />described az representative for the series, but the
<br />surface layer is about 6 inches thick and the sub-
<br />soil is about 20 inches thick. Depth to lime ranges
<br />from 8 to 24 inches.
<br />Included with these soils in mapping are small
<br />areas of Buick loam, Bresser sandy loam, 3 to 9
<br />percent slopes, Truck ton sandy loam, 3 to 8 percent
<br />slopes, and a sandy soil that is similar to Newlin
<br />soils except that it contains less gravel and has a
<br />layer of lime. Taken together, these areas make up
<br />about 20 percent of each mapped area.
<br />Runoff is medium. The erosion hazard is slight.
<br />Soil slippage takes place in areas that have slopes
<br />exceeding 15 percent.
<br />Most areas of these soils are in native grass and
<br />are used for grazing livestock and wildlife habitat.
<br />Brush, ponderosa pine, and juniper are present. In
<br />places these are source areas for gravel. (Newlin
