COMPETING SERIES: These are the Aguja (NM), Finleypoint (MT),
Flott (MT), Kutler (CO),
Labre (MT),
Perma (MT),
Peso (NM),
Renegade (UT), Slimbutte (SD), Subwell (MT),
Towave (UT),
Veatch (CO),
Vigilante (MT),
Walstead (MT),
Wanagan (ND) and
Wimper (MT) series.
Finleypoint soils: are very deep, have an albic horizon and are derived from glacial till.
Flott soils: have a calcic horizon.
Kutler soils: have a paralithic contact between 20 to 40 inches and are derived from granite. Kutler soils are in the 17 to 20 inch rainfall zone.
Labre soils: are very deep
Perma soils: have carbonates accumulated in the C horizons. Perma soils have 40 to 80 percent gravel in the 10- to 40-inch section.
Peso soils: have Bk horizons with 6 to 15 percent calcium carbonate equivalent; have bedrock at depths of 20 to 40 inches; have carbonates accumulated in the C horizons and formed in parent material derived from limestone
Renegade soils: have paralithic contact between 40 to 60 inches.
Slimbutte soils: are calcareous at a shallow depth and fragmental below 40 inches.
Subwell soils: have a discontinuity at 10 to 20 inches, secondary carbonate accumulation and are non-skeletal above the discontinuity.
Towave soils: do not have a cambic horizon.
Veatch soils: derived from sedimentary parent material and are deep.
Vigilante soils: deep
Walstead soils: have calcic horizons
Wanagan soils: calcareous at shallow depths and contain a lithologic discontinuity at 12 to 20 inches.
Wimper soils: have calcic horizons and deep
GEOGRAPHIC SETTING: The Sandia soils are on strongly sloping to moderately steep mountain slopes. Elevation ranges from 8,400 to 9,500 feet. The soils formed mainly in materials from sandstone. Annual precipitation is about 18 to 25 inches. The annual temperature ranges from 43 to 47 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Kolob soils. Kolob soils have a clayey-skeletal control section. Rock outcrop is an associated miscellaneous land type.
DRAINAGE AND PERMEABILITY: Well-drained; medium runoff; moderate permeability.
USE AND VEGETATION: These soils are used for timber production, rangeland, recreation, water production, and wildlife habitat. Principal native vegetation is Douglas-fir, white fir, ponderosa pine, Gambel oak, junegrass, mountain brome, western yarrow, and pine dropseed.
DISTRIBUTION AND EXTENT: Mountains of central New Mexico. The series is of moderate extent. MLRAs 39 & 48A.
