<br />Otero soils are mapped only with Ascalon soils in this
<br />survey area.
<br />~Pey on Series
<br />The Peyton series is made up of deep, well-drained
<br />soils. These soils formed on upland hills and valley side
<br />slopes in weathered loamy and sandy material that has
<br />been locally transported. Slopes are 5 to 20 percent.
<br />Elevations are 5,800 to 7,500 feet. The vegetation is
<br />mainly tall h •asses and, in places, ponderosa pine. An-
<br />nual precipitation is 18 to 24 inches. Mean annual air
<br />temperature is 44° to 48° F., and the frost-free season is
<br />about SO to 120 days.
<br />In a representative profile the surface layer is dark-
<br />gray very gravelly loamy sand about 11 inches thick.
<br />The subsoil, about 32 inches thick, is brown, gravelly
<br />sandy clay loam that grades to gravelly coarse sandy
<br />loam. The srlbstra.tum extending to a depth of 60 inches
<br />or more is pale-brown gravelly sandy loam. Soil reaction
<br />is neutral.
<br />Peyton soils have moderate permeability. Available
<br />water capacity for the profile >s moderate. ,Roots can
<br />penetrate to n depth of 40 to 60 inches or more.
<br />These soils are used far pustule and homesites.

<br />the surface Isyer contains up to 80 percent coarse ftag-
<br />meats.

<br />pe cent-slo es gEl•-This complex rs on the uplands in
<br />the western part of the Area, These are open parklike
<br />areas mainly more than 20 acres in size. This complex
<br />consists of about 65 percent Peyton very gravelly loamy
<br />sand and about 20 percent ,7uget very gravelly loamy
<br />sand. Peyton very gravelly loamy sand is in the moan
<br />part of the Wren. Juget very gravelly loamy sand is
<br />around fire edges of the areas and on narrow ridges ex-
<br />tending into the areas. The Peyton soil has the profile
<br />described as representative for the Peyton series. The
<br />Jugot soil has a profile much like that described as rep-
<br />resentative for the Juget series, but the surface layer is
<br />very gravelly loamy sand.
<br />Included with this complex in mapping are small
<br />areas of Rock outcrop and a few small areas of Aliens
<br />Park soils. Also included along some drainageways are
<br />auras of a deep, dark-colored soil formed in alluvium. A
<br />few small areas around lakes or ditches have a seasonal
<br />high water table. The included soils make up about 15
<br />percent of each mapped area.
<br />Runoff is slow to medium on this complex. The ero-
<br />sion hazard is moderate to high. Tillage of most areas
<br />is limited by the amount of gravel.
<br />All the acreage of this complex is used for pasture,
<br />recreational uses, and wildlife habitat. Some areas are
<br />used for homesites. (Capability unit VIIs-1, nonirrigated;
<br />tree suitability group 2)
<br />Pinata Series
<br />The Pinata series is made up of moderately deep, well-
<br />drained soils that formed on upland ridges and side
<br />sloes. These soils developed in stony sandy to clayey
<br />residuum and coluvium weathered from sandstone and
<br />shale. Slopes are 5 to 55 percent. Elevations are 6,000 to
<br />7,000 feet. The native vegetation is mainly ponderosa
<br />pine with n sparse understory of grass. Annual precipita-
<br />tion is 14 to 18 inches. Mean annual air temperaature is 47°
<br />to 51° F.. and the frost-free Benson is about 100 to 130
<br />days.
<br />In a representative profile (fig. 3) the srrface layer
<br />is brown very stony loamy fine sand about 3 inches thick.
<br />The subsurface layer, about 9 inches thick, is pink very
<br />stony loe,my fine sand. The subsoil is a red very stony
<br />clay, about 20 inches thick, that overlies sandstone. Sort
<br />reaction is slightly acid.
<br />Pinata soils have slow permeability. Available water
<br />capacity for the profile is moderate. Roots can penetrate
<br />to s depth of between 20 and 40 inches.
<br />These soils are used mainly for pasture and as a source
<br />of quarried sandstone. Some areas have n limited use
<br />for forestry.
