<br />
<br />Elevation is 6,000 to 8,600 feet. The average annual
<br />precipitation is about 11 to 20 inches, the av"rage
<br />annual air temperature is 40 to 54 degrees F, and the
<br />average frost-free season is 75 to 130 days.
<br />The soils in this group are shallow to deep and are
<br />well drained. They formed in residuum, collu~ium,
<br />alluvium, and eolian material derived dominantly from
<br />sandstone, siltstone, shale, and a few areas of igneous
<br />rock.
<br />This group is used as rangela,nd, woodland, and
<br />wildlife habitat.
<br />
<br />7. Louviers- Travessilla
<br />
<br />Shallow, well drained, gently sloping to vel}' ste,9p soils;
<br />on ridges and side slopes of dissected plateaus
<br />
<br />This map unit is in the central part of the survey area.
<br />Slope is 3 to 65 percent. The vegetation is mainly pinyon
<br />and juniper. Elevation is 6,300 to 7,500 feet. Th"
<br />average annual precipitation is about 14 to 1 Ei inches,
<br />the average annual air temperature is 48 to 54 degrees
<br />F, and the average frost-free season is 100 to 130 days.
<br />This unit makes up about 4 percent of the survey area.
<br />It is about 35 percent Louviers soils and 30 percent
<br />Travessilla soils. The remaining 35 percent is
<br />components of minor extent.
<br />Louviers soils are on side slopes of dissect'3d
<br />plateaus. These soils are shallow and well drained. They
<br />formed in residuum derived dominantly from clayey
<br />shale. The soils are fine textured or moderately fine
<br />textured and are underlain by shale at a depth of 16
<br />inches.
<br />Travessilla soils are on ridges and side sloees of
<br />dissected plateaus. These soils are shallow and well
<br />drained. They formed in residuum derived dominantly
<br />from sandstone. The soils are moderately coarse
<br />textured and are underlain by sandstone at a jepth of 15
<br />inches.
<br />Of minor extent in this unit are deep Noden. I\unn,
<br />and Olney soils and moderately deep Progres 50 soils.
<br />This unit is used as woodland and for livestock
<br />grazing.
<br />Wildlife such as mule deer, cottontail, squirrel,
<br />porcupine, coyote, and limited numbers of turkey and
<br />mourning dove inhabit this unit.
<br />This unit is poorly suited to homesite develc pment.
<br />The main limitations are shallow depth to bedrock and
<br />steepness of slope.
<br />
<br />8. Farisila-Olney-Progresso
<br />
<br />Shallow to deep. well drained, gently sloping t.o \'el}'
<br />steep soils; on ridges, side slopes, and uplana:,
<br />
<br />This map unit is in the central and west-cenlral parts
<br />of the survey area. Slope is 3 to 35 percent. The
<br />vegetation is mainly grass on the more gently sloping
<br />soils and pinyon and juniper on the steeper soils
<br />Elevation is 6.000 to 7,300 feet. The average annual
<br />
<br />Soil survey
<br />
<br />precipitation is about 13 to 17 inches, the average
<br />annual air temperature is 46 to 52 degrees F, and the
<br />average frost-free season is 100 to 130 days.
<br />This unit makes up about 7 percent of the survey area.
<br />It is about 25 percent Farisita soils, 20 percent Olney
<br />soils, and 10 percent Progresso soils. The remaining 45
<br />percent is components of minor extent.
<br />Farisita soils are sloping to steep and are on ridges
<br />and side slopes. These soils are shallow and well
<br />drained. They formed in residuum and colluvium derived
<br />dominantly from conglomeratic sandstone. The soils are
<br />moderately coarse textured and are underlain by
<br />sandstone at a depth of 12 inches.
<br />Olney soils are gently sloping and are on uplands.
<br />These soils are deep and well drained. They formed in
<br />eolian material. The surface layer is moderately coarse
<br />textured. The subsoil is moderately fine textured. Below
<br />this, to a depth of 60 inches or more, the soils are
<br />moderately coarse textured.
<br />Progresso soils are in the more steeply sloping areas
<br />on uplands. These soils are moderately deep and well
<br />drained. They formed in residuum derived dominantly
<br />from sandstone. The surface layer is moderately coarse
<br />textured. The subsoil is moderately fine textured. Below
<br />this, to a depth of of 24 inches, the soils are moderately
<br />coarse textured. Unweathered sandstone is at a depth of
<br />24 inches.
<br />Of minor extent in this unit are excessively drained
<br />Schamber soils, somewhat excessively drained Otero
<br />soils, and well drained Noden and Bond soils. The
<br />Schamber, Otero, and Noden soils are deep. The Bond
<br />soils are shallow to sandstone.
<br />This unit is used as rangeland, woodland, and wildlife
<br />habitat.
<br />Wildlife such as mule deer, cottontail, jackrabbit,
<br />coyote, bobcat, porcupine, squirrel, and limited numbers
<br />of turkey and mourning dove inhabit the unit.
<br />If this unit is used for homesite development, the main
<br />limitation is depth to rock.
<br />
<br />9. Noden-Bond
<br />
<br />Shallow and deep, well drained, gently sloping to
<br />moderately sloping soils; on uplands, foot slopes, and
<br />ridges
<br />
<br />This map unit is in the south-central and west-central
<br />parts of the survey area. Slope is 1 to 18 percent. The
<br />vegetation is mainly grass on the uplands and foot
<br />slopes, and it is mainly pinyon and juniper on the ridges.
<br />Elevation is 6,200 to 7,500 feet. The average annual
<br />precipitation is about 15 to 18 inches, the average
<br />annual air temperature is 47 to 52 degrees F, and the
<br />average frost-free season is 100 to 125 days.
<br />This unit makes up about 7 percent of the survey area.
<br />It is about 55 percent Noden soils and 20 percent Bond
<br />soils. The remaining 25 percent is components of minor
<br />extent.
<br />Noden soils are on uplands and foot slopes. These
<br />soils are deep and well drained. They formed in mixed
