<br />residuum and colluvium derived dominantly Ire m
<br />interbedded sandstone, siltstone, and shale The soils
<br />are very channery and extremely channery. Hley are
<br />medium textured and are underlain by siltston" at a
<br />depth of 11 inches.
<br />Patent soils are on fans and foot slopes clnel in swales.
<br />These soils are deep and well drained. They formed in
<br />alluvium derived dominantly from sandstone. The soils
<br />are medium textured throughout.
<br />Of minor extent in this unit are Noden, Bond, Tolman,
<br />and Utica soils and Rock outcrop. The NodEln and Utica
<br />soils are deep. The Utica soils are excessiv"ly drained.
<br />The Bond and Tolman soils are shallow over sandstone.
<br />Most areas of this unit are used as rangeland. A few
<br />areas of the Patent soils are used as irrigatE,d cropland.
<br />Wildlife such as mule deer, cottontail, squ rml,
<br />porcupine, bobcat, and coyote inhabit this unit. In
<br />addition, limited numbers 01 antelope are on the Patent
<br />soils and elk are on the Castner soils. Areas used as
<br />cropland provide additional food and cover.
<br />The more gently sloping areas of this unit are well
<br />suited to homesite development, but the ste"per areas
<br />are poorly suited. The main limitations are slope and
<br />depth to rock.
<br />
<br />12. Ustic Torriorthents-Neville-Potts
<br />
<br />Shallow to deep, well drained, gently sloping to steep
<br />soils; on side slopes and uplands and in drainageways
<br />
<br />This map unit is in the western and northwestern parts
<br />of the survey area. Slope is 1 to 40 percent. Tile
<br />vegetation is mainly grass. Pinyon and juniper are on the
<br />steeper slopes. Elevation is 6,/'00 to 7,600 f,"e':. The
<br />average annual precipitation is about 11 to 14 Inches,
<br />the average annual air temperature is 47 to !52 degrees
<br />F, and the average frost-free season is 100 1:0 125 days.
<br />This unit makes up about 8 percent of the sLlrvey area.
<br />It is about 25 percent Ustic Tor riorthents, 20 percent
<br />Neville soils, and 15 percent Potts soils. The rEmaining
<br />40 percent is components of minor extent.
<br />Ustic Torriorthents are extremely rough and "roded
<br />soils. They are mainly on side slopes of deeply dissected
<br />terraces. These soils are shallow and moderatE,ly deep
<br />and are well drained. They formed in residuum and
<br />colluvium derived dominantly from siltstone c.nd shale.
<br />The soils are moderately fine textured. They ar.,
<br />underlain by siltstone at a depth of 12 to 40 ,nches.
<br />These soils are slightly salt- and alkali-affected in some
<br />areas.
<br />Neville soils are on side slopes and uplands and in
<br />drainageways. These soils are deep and well drained.
<br />They formed in alluvium and colluvium derived
<br />dominantly from sandstone, siltstone, and shale. The
<br />soils are medium textured throughout.
<br />Potts soils are on uplands. These soils are d"ep and
<br />well drained. They formed in eolian material and In
<br />alluvium derived dominantly from sandstone. The surface
<br />layer is moderately coarse textured. The sub"oil is
<br />
<br />Soil survey
<br />
<br />moderately fine textured. Below this, to a depth of 60
<br />inches or more, the soils are medium textured or
<br />moderately coarse textured.
<br />Of minor extent in this unit are excessively drained
<br />Schamber soils, Brownsto soils. and Rock outcrop. The
<br />Brownsto soils are deep and have many rock fragments.
<br />Rock outcrop occurs as barren sandstone escarpments
<br />and exposed areas of shale.
<br />Most areas of this unit are used for wildlife habitat. A
<br />few areas are used for Irrigated hay and pasture. The
<br />Potts and Neville soils are well suited to irrigated hay
<br />and pasture.
<br />Wildlife such as mule deer, mourning dove, cottontail,
<br />bobcat, badger, skunk, and coyote inhabit this unit.
<br />Limited numbers of turkey also inhabit the unit. Areas
<br />used as cropland provide additional food, and
<br />windbreaks and environmental plantings provide
<br />additional cover.
<br />Except for the steeper slopes, this unit is well suited to
<br />homesite development. The main limitations are the
<br />hazard of erosion and depth to soft rock.
<br />
<br />soils on mountains
<br />
<br />This group consists of seven map units. It makes up
<br />about 18 percent of the survey area. The soils in this
<br />group are gently sloping to extremely steep. The native
<br />vegetation is mainly grass and conifers. Elevation is
<br />6,800 to 12,000 feet. The average annual precipitation is
<br />about 14 to 30 inches, the average annual air
<br />temperature is 36 to 47 degrees F, and the average
<br />frost-free season is 30 to 100 days.
<br />The soils in this group are shallow to deep and are
<br />well drained. They formed in alluvium, colluvium, and
<br />residuum derived from granite, igneous rock, sandstone,
<br />siltstone, and shale.
<br />This group is used as woodland and rangeland and for
<br />wildlife habitat and recreation.
<br />
<br />13. Maitland-Bayerton-Ring
<br />
<br />Moderately deep and deep, well drained, gently sloping
<br />to vel}' steep soils; on mountainsides, foot slopes,
<br />uplands. and terraces
<br />
<br />This map unit is in the western part of the survey area.
<br />Slope is 1 to 60 percent. The vegetation is mainly
<br />ponderosa pine. Elevation is 6.800 to 8,500 feet. The
<br />average annual precipitation is about 18 to 23 inches,
<br />the average annual air temperature is 38 to 47 degrees
<br />F, and the average frost-free season is 60 to 100 days.
<br />This unit makes up about 4 percent of the survey area.
<br />It is about 20 percent Maitland soils, 20 percent
<br />Bayerton soils, and 15 percent Ring soils. The remaining
<br />45 percent is components of minor extent.
<br />Maitland soils are on uplands and foot slopes. These
<br />soils are deep and well drained. They formed in
<br />colluvium derived dominantly from sandstone and shale.
<br />The surface is covered with a mat of twigs and needles.
