<br />14 SO[L SURVEY
<br />Keith clay loam. Bainville silt loam is steeper, and
<br />Keith clay loam is n•rore nearly level and is in de-
<br />pressions. The Bainv's'Ile soil has the profile described
<br />:es representative of 'the Bainville set•res. The Keith
<br />soil has a profile similar to the' one described as rep-
<br />resentative of the Keiith series, but the surface layer
<br />is clay loam.
<br />Included ~sith these soils in mapping is about 15 per-
<br />cent Larim and Epping soils.
<br />Runoff is medium, and the hazard of erosion i mod-
<br />erate.
<br />These soils are well suited to pasture <1nd native
<br />gt•asses and are used rnainly for these purposes. A few
<br />small areas are used 1'oi• dryfarmed wheat. Capability
<br />unit IVe-3, dr•ytand; Bainville soil in Loamy Foothill
<br />range site and I{eith soil in Clayey Foothill range site;
<br />not assigned to a windbreak suitability group.
<br />Baller Series
<br />The Baller series consists of shallow, well drained
<br />soils that formed in material weathered from sand-
<br />stone. These soils are on uplands and ar'e undet•lain by
<br />bedrock at a depth of 10 to 20 inches. Elevation ranges
<br />from 5,400 to 6,800 l.'eet. Slopes are 5 to 45 percent.
<br />The native vegetation is mainly big and little bluestem,
<br />blue grama, side-oats grama, mountainmahogany, and
<br />a few scattered ponds>rosa pine. Mean annual precipi-.
<br />tation ranges from 1!i to 17 inches, mean annual air
<br />temperature ranges from 47° to 49° F, and the frost-
<br />free season ranges from 135 to 150 days.
<br />in a representative profile the surface layer is dark
<br />gz•ayish brown stony ;sandy loam about 6 inches thrck.
<br />The subsurface layer is dark grayish brown very stony
<br />sandy loam about 5 inches thick. Below this is hard
<br />sandstone.
<br />Permeability is moderately rapid, and the available
<br />water capacity is low. Reaction is neutral.
<br />These soils ai-e used for native grasses.
<br />Representative profile of Baller stony sandy loam in
<br />an area of Baller-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 this southeast corner of sec. 32, T.
<br />7 N., R. 69 1V.
<br />A1--0 to 6 inches; dark grayish brown (lOYR
<br />4/2) stc-ny sandy loam, very dark gray-
<br />ish brown (lOYR 3/2) moist; weak to
<br />moderate fine granular structure; soft,
<br />very friable; 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; sofft, very friable; 60 percent stones
<br />and cobbles; noncalcareous; neutral.
<br />R--II inches; hard 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 />II-Baller-Carnero complex, 9 to 35 percent elopes.
<br />This complex consists of strongly sloping to steep soils
<br />on ridges. It is about 45 percent Baller stony sandy
<br />loam and about 35 percent Carnero loam. The soils are
<br />intermingled in an intricate pattern, but Baller• stony
<br />sandy loam commonly is on the upper part of the
<br />ridges and Carnero loam is near the bottom of the
<br />scope and is less sloping. The Baller soil has a profile
<br />similar to the one described as representative of the
<br />Baller series- The Carnero soil has a profile similar to
<br />the one described as representative of the Carne-~o
<br />series, but more cobbles and stones are on tl~e surface.
<br />Included with t{tese soils in mapping a-•e about 20
<br />percent areas of Rock outcrop and extremely stony
<br />soils that are similar to Carnero soils but in ~v}~ich
<br />sandstone is at a depth of less than 20 inches.
<br />Runoff is rapid, and the Hazard of erosion is severe.
<br />These soils are suited to native grasses. Capability
<br />unit VIis-1, dryland; Baller soil in Shallow• Foothill
<br />range site and Carnero soil in Loamy Foothill range
<br />site; not assigned to a windbreak suitability group.
<br />12---Baffer-Rock outcrop complex, 15 to 4S percent
<br />slopes. This complex consists of strongly sloping to
<br />steep soils on ridges and "hogbacks." It is about 50
<br />percent Baller stony sandy loam and about 30 percent
<br />Rock outcrop. Baller stony sandy loam is mainly on
<br />east-facing side slopes on the ridges. Rock outcrop is
<br />mainly near ridgetops, but it is scattered throughout.
<br />The Baller soil has t}ie profile described as representa-
<br />tive of the Baller series.
<br />Included with this complex in mapping is about 20
<br />percent Carnet•o soils and areas of a soil that is similar
<br />to the Baller soil but that has a clayey subsoil.
<br />Runoff is rapid, and the hazard of erosion is se~'ere.
<br />This complex is suited to native grasses. Capability
<br />unit VIIs-1, dryland; Baller• soil in Shallow Foothill
<br />t•ange site and Rock outcrop not assigned to a range
<br />site; not assigned to a windbreak suitability group.
<br />Barnum Series
<br />The 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, wheatgrasses, and cactus.
<br />Mean annual precipitation ranges from 15 to 18
<br />inches, mean annual air temperature ranges 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 layer is
<br />brown 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 />Representative profile of Barnum loam in an area of
<br />Connerton-Barnum complex, 0 to 3 percent slopes, in
<br />native grass, 1,650 feet south of center of sec. 30, T.
<br />10 N., R. 69 W.:
<br />A1--0 to 10 inches; brown (7.5YR 5/3) loam,
<br />brown (7.5YR 4/3) moist; weak medium
<br />subangular blocky and weak medium
<br />granular structure; slightly hard, very
<br />friable; calcareous; moderately alkaline;
<br />clear smooth boundary.
