<br />PmE-Penrose-Minnequa complex, 1 to 16 percent
<br />slopes. This complex is in all but the northeastern and
<br />western parts of the survey area. It is made up of
<br />about 80 percent Penrose channery loam, and the teat
<br />ie equal parts of Manvel silt loam and Minnequa loam.
<br />Areas of this complex are irregularly shaped and cover
<br />as much ae 800 acres. The Minnequa and Manvel gone
<br />are on the more level areas at the low end of the eloping
<br />Penrose soils.
<br />The Penroge, Minnequa, and Manvel voile 1n this
<br />complex have the profile described ae representative of
<br />their aeries.
<br />Included with these soils in mapping are areas of
<br />Rock outcrop that make up about 10 percent of the
<br />acreage.
<br />RunoR ie rapid, end the hazard o[ erosion is ellght.
<br />This complex Is better suited to grazing and wildlife
<br />habitat than to other uses. The native vegetation is
<br />mainly blue grams, aide-0ate grams, New Mexico
<br />needlegrass, Indian ricegrage, yucca, Bigelow eage-
<br />bruah, and some pinyon pine, juniper, akunkbueh, and
<br />mountainmahogany. Capabllltyy unit VIIs~, nonirrf-
<br />gated; Penrose Boll In Llmeatone Hreaka range site;
<br />Manvel srid Minnequa voile in Loamy Plains range Bite.
<br />Stroupe Series
<br />The Stroupe series consists of moderately deep, well-
<br />drained voile. These Boils lormed on mesas and foat-
<br />hllle 1n clayey residuum weathered from eandetone.
<br />They ere underlain by eandetone at a depth of 20 to
<br />40 inches. The elope le 9 to 26 percent, and elevation to
<br />6,800 to 8,600 feet. The average annual precipitation to
<br />18 Inches. The aver a annual temperature le 47° F,
<br />and the frost-free ee~on le 116 to 146 days. The native
<br />v elation is mainly foothill grasses and shrubs.
<br />In s representative profile the surface layer ie brown
<br />extremely stony loam abou! 4 Inehee thlek. The upper
<br />part of the eubeoll le brown very stony loam about
<br />6 Inehee thick, and the lower part le reddish-brown
<br />very etany clay loam about 18 inches thick. Sandstone
<br />bedrock le at a depth of about 26 inches.
<br />Permeability ie slow, and the available water ca-
<br />pacity le low. The surface layer and eubeoll are neutral,
<br />and the underlying materiel fe neutral or mildly alka-
<br />Ilne. The took zone extends to a depth of 20 to 40
<br />Inehee. These soils are used almost exclusively for

<br />This soli le salted to grazing. It has potential for

<br />production le limited by the low available moisture

<br />juniper woodland, end the rest 1e grassland. The native
<br />v station le mainly western wheatgraee, blue graroa,
<br />Bide-oats Brame, yucca, cactus, mountainmahogany,

<br />irrigated; S~lallow Foothills range gate.
<br />Wormser Series
<br />The Wormser aeries consists of moderately deep,
<br />well-drained soils. These soils formed on sandstone
<br />uplands in silty loess and loamy residuum weathered
<br />from eandetone. They are underlain by eandetone be-
<br />tween depths of 20 and 40 inches. The elope ie 1 to 4
<br />percent, and elevation is 6,800 to 7,000 feet. The
<br />average annual precipitation ie 17 inches. The average
<br />annual temperature ie 60° F, and the frost-free season
<br />ie 180 to 140 days. The native vegetation ie mainly
<br />short plains grasses.
<br />In syrepresentative profile the surface layer ie
<br />grayish-brown silty clay loam and brown clay loam
<br />about 16 inches thick, and the lower part ie pale-brown
<br />clay loam about 6 inches thick. The underlying material
<br />ie very pale brown clay loam about B inches thick.
<br />Sandstone ie at a depth of about 88 inches.
<br />Permeability ie glow, and the available water ca-
<br />padty ie moderate. The surface layer ie neutral, and
<br />the subsoil ie moderately alkaline. The root zone ex-
<br />tends to a depth of 20 to 40 inches. These soils are used
<br />for range, wildlife habitat, and watershed.
