<br />l4 SOIL SURVEY
<br />Keith clay loam. Bainville silt loam is steepet•, and
<br />Keith clay, loam is more nearly level and is in de-
<br />lzz•essions. The B:linville soil has the pt•ofiie described
<br />:-s representative of the Bainville series. The Keith
<br />soil h<1s a profile similar to the one described as rep-
<br />resentative of the Keith series, but the sut•face layer
<br />1S Clay loam.
<br />Included \\•ith these soils in mapping is about 15 per-
<br />cent Larim and Epping soils.
<br />Runoff is medium, and the hazard of erosion is mod-
<br />erate.
<br />These soils are well suited to pasture and native
<br />grasses and are used mainly for these PPurposes. A few
<br />small areas are used :for dryfarmed wheat. Capability

<br />range site and Keith sort in Clayey Foothill range site;
<br />not assigned to a irin~dbreak suitabrlity gz•oup.
<br />Bailer Series
<br />The Biller series consists of shallow, welt drained
<br />soils that formed in material weathered from sand-
<br />stone. These soils are on uplands and at•e undet•lain by
<br />bedrocl; at a depth of 10 to 20 inches. Elevation ranges
<br />from 5,400 to 6,800 Meet. Slopes are 5 to -15 percent.
<br />The native vegetation is mainly big and little bluestem,
<br />blue grama, side-oats grama, mountainmahogany, and
<br />a few scattez•ed ponderosa pine. Mean annual precipi-.
<br />tation ranges fz•om 15 to 17 inches, mean annual aiz•
<br />temperature ranges from 97° to 9~J° F, and the frost-
<br />fr•ee season ranges from 135 to 150 days.
<br />In a representative profile the surface layer is dark
<br />gt•ztyislt brown stony sandy loam about 6 inches thick.
<br />The subsurface layer is dat•k grayish brown very stony
<br />sandy loam about 5 inches thick. Below this is haz•d
<br />sandstone.
<br />ipet•meability is moderately rapid, and the available
<br />\vater capacity is low. Reaction is neutral.
<br />These soils az-e used for native grasses.
<br />Representative profile of Biller stony sandy loam in
<br />an area of Biller-Rock outcrop complex, 15 to 45 per-
<br />cent slopes, in native grass, about 1,050 feet west and
<br />1,650 feet north of the southeast corner of sec. 32, T.
<br />7 N., R. 69 \V.:
<br />A1-0 to 6 inches; dark grayish brown (IOYR
<br />4/2) st~~ny sandyy loam, very dark gray-
<br />ish brown (1OYR 3/2) moist; weak to
<br />rnoderal~e fine granular structure; soft,
<br />very friiable; 25 percent stones and cob-
<br />bles; noncalcareous; neutral; clear
<br />smooth boundary.
<br />AC-6 to 11 inches; dark grayish brown (lOYR
<br />4/2) very stony sandy loam, very dark
<br />grayish brown (10YR 3/2) moist; mas-
<br />sive; soft, very friable; 60 percent stones
<br />and cobbles; noncalcareous; neutral.
<br />R-I1 inches; hrard sandstone bedrock.
<br />The A horizon is sandy loam or fine sandy loam and
<br />contains 35 to 70 percent stones or cobbles, mainly of
<br />sandstone. Reaction ranges from slightly acid to mildly
<br />alkaline.
<br />11-Bailer-Carnera~ complex, 9 to 35 percent elopes.
<br />This complex consists of strongly sloping to steep soils
<br />on ridges. It is about 45 percent Bailer stony sandy
<br />' loam and about 35 percent Carnero loam. The soils are
<br />intermingled in an intt•icate pattern, bztt Ballez• stony
<br />sandy loam commonly is on the upper part of the
<br />ridges and Carnero loam is near. the bottom of the
<br />slope and is less sloping. The Ballez• soil has a profile
<br />similaz• to the one described as representative of the
<br />Bailer sez~ies. The C~u•nero soil has a profile similar to
<br />the one described as representative of the Carnero
<br />series, but more cobbles and stones are on the surface.
<br />Included with these soils in mapping are about 20
<br />percent areas of Rock outcrop and extremely stony
<br />sorts that are similar to Carnero soils but in n•hich
<br />sandstone is at ;\ depth of less than 20 inches.
<br />Runoff is z•apid, and the hazard of et•osion is sevez•e.
<br />These soils are suited to native grasses. Capability

<br />1~-Biller-Rock outcrop complex, 15 to 45 percent
<br />elopee. This complex consists of strongly sloping to
<br />steep soils on ridges and "hogbacks." It is about 50
<br />percent Biller stony sandy loam and about- 30 pez•cent
<br />Rock outcrop. Bailer stony sandy loam is mainly on
<br />east-facing side slopes on the t•idges. Rock outcrop is
<br />mainly neat• ridgetops, but it is scattet•ed throughout.
<br />The. Biller soil has t}ie pz•ofile described as rept•esenta-
<br />tive of the Bailer series.
<br />Included \vith this complex in mapping is about 20
<br />pet•cent Carnet•o soils and areas of a soil that rs similar
<br />to the Baliet• soil but that has a clayey subsoil.
<br />Runoff is rapid, and the hazard of erosion is se\'ere.

<br />Barnum Series
<br />Tlie Barnum series consists of deep, well drained
<br />soils that formed in alluvium from reddish colored
<br />shale and sandstone. These soils are in upland valleys
<br />and bottom lands. Elevation ranges from 5,200 to
<br />6,300 feet. Slopes are 0 to 5 percent. The native vege-
<br />tation is mainly blue grama, \vheatgrasses, and cactus.
<br />Mean <•innual precipitation ranges from 15 to 18
<br />inches, mean annual air temperature t•anges from 47°
<br />to 49° F, and the frost-free season ranges from 115 to
<br />130 days.
<br />In a representative profile the surface Payer is
<br />bro\vn loam about 10 inches thick. The underlying ma-
<br />terial is reddish brown loam stratified with thin layers
<br />of sandy loam and is about 50 inches thick.
<br />Permeability is moderate, and the available water
<br />capacity is high. Reaction is moderately alkaline.
<br />These soils are used for irrigated and dryfarmed
<br />crops and native grasses.

<br />Connerton-Barnum complex, 0 to 3 percent slopes, in

<br />10 N., R. 69 W.:
<br />A]-0 to IO inches; brown (7.5YR 5/3) loam,
<br />brown (7.5YR 4/3) moist; \veak medium
<br />subangular blocky and \veak medium
<br />granular structure; slightly hard, very
<br />friable; calcareous; moderately alkaline;
<br />clear smooth boundary.
