RANGE IN CHARACTERISTICS:
Soil Moisture: Aridic ustic moisture regime. The moisture control section is usually dry in some or in all parts for six-tenths or more of the time that the soil temperature exceeds 41 degrees F. Some part of the epipedon is moist for more than 90 cumulative days in most years when the soil temperature exceeds 41 degrees F.
Mean annual soil temperature: 59 to 62 degrees F.
Thickness of mollic epipedon: 20 to 40 inches
Particle-size control section weighted average:
Clay content: 10 to 18 percent
Coarse fragment content: 60 to 80 percent
Reaction: strongly acid to slightly acid
A horizon:
Hue: 5YR or 7.5YR
Value: 3 or 4 dry, 2 or 3 moist
Chroma: 1 to 3, dry or moist
Coarse fragments: mixed igneous fragments; 35 to 60 percent coarse fragments, 35 to 55 percent gravel, 0 to 10 percent cobbles
C horizons:
Hue: 5YR or 7.5YR

COMPETING SERIES: There are no competing series.
GEOGRAPHIC SETTING:
Parent material: Alluvium from monzonite and tuff
Landform: Stream terrace
Slope: 0 to 3 percent
Mean annual temperature: 58 to 61 degrees
Mean annual precipitation: 13 to 15 inches
Precipitation pattern: Precipitation falls mostly during the months of July through September. The driest months are March and April. Precipitation during the months of January, February, and March is less than 13 percent of the total.
Frost-free period: 140 to 180 days
Elevation: 4,700 to 6,300 feet
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Thaad,
Brewster,
Poblano, and
Arbol soils.
Brewster and Arbol soils are shallow to very shallow and are on mountain tops and flanks.
Thaad and Poblano soils are moderately deep to bedrock and are on mountain flanks and bases.
DRAINAGE AND PERMEABILITY: Well drained. Permeability is moderately slow over rapidly permeable. Runoff is medium.
USE AND VEGETATION: Used for livestock grazing. Vegetation is of the mixed prairie type consisting of sideoats grama, blue grama, oak spp., Apache plume, and alligator juniper.
DISTRIBUTION AND EXTENT: Southern New Mexico; LRR D, MLRA 42. The series is of minor extent.

REMARKS: Diagnostic horizons and features recognized in this pedon are:
Particle-size control section: The zone from 10 to 40 inches. (C1, C2, 2C3 and 2C4 horizons)
Mollic epipedon: The zone from 0 to 34 inches. (A, C1, C2, 2C3)
The assignment of the cation exchange capacity is inferred from lab data from similar soils in the surrounding area.
