C2--26 to 65 inches; yellowish brown (10YR 5/4) loamy fine sand, brown (10YR 4/3) moist; single grain; loose, very friable, nonsticky and nonplastic; few medium, fine and very fine roots; many very fine irregular pores; slightly alkaline (pH 7.8).
TYPE LOCATION: McKinley County, New Mexico; Starlake Quadrangle; about 3 miles northwest of Starlake trading post; about 1100 feet east and 650 feet south of the northwest corner of Sec. 29 T. 20 N, R. 6 W.; 107 degrees 29 minutes 45 seconds west longitude, 35 degrees 56 minutes 28 seconds north latitude.
RANGE IN CHARACTERISTICS:
Soil Moisture: The SMCS is usually dry, in all parts, 105 to 160 cumulative days from April through October. It is usually moist, in some part, 50 to 105 cumulative days during the same period. It is intermittently moist in some part November through April. The period of maximum precipitation is July through October. The soil is driest during May and June. Ustic aridic moisture regime.
Soil Temperature: 48 to 55 degrees F.

COMPETING SERIES: These are the Curtis Siding (WY), Dwyer (WY), Karval (CO), Mido (UT), Orpha (WY), Pensom (AZ), Pinavetes (NM), Tullock (WY), Valent (CO), and Wigton (CO) series. Curtis Siding soils are inactive. Dwyer, Karval, Orpha, Valent, and Wigton soils are moist in the soil moisture control section during May and June. Mido soils have hues redder than 7.5YR and a higher precipitation range. Pensom soils are deep to sandstone. Tullock soils are moderately deep. Pinavetes soils have soil temperatures of 53 to 57 degrees F., 10 to 14 inches precipitation, and are effervescent in the control section.
GEOGRAPHIC SETTING: The Calladito soils formed in eolian materials derived from sandstone. Calladito soils form dunes on stream terraces, fan remnants, and on dipslopes and summits of cuestas and mesas. Slopes are 1 to 8 percent. Elevations range from 6,300 to 6,800 feet. The mean annual temperature is 46 to 53 degrees F., and the mean annual precipitation is 8 to 10 inches. The frost free period is 100 to 145 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Betonnie, Councelor, Doakum, Elias, and Eslendo soils. The Betonnie and Councelor soils are very deep, coarse-loamy, on fan remnants and stream terraces. The Doakum soils are very deep, fine-loamy, on fan remnants. The Elias soils are very deep, fine textured, on fan remnants and knolls. The Eslendo soils are shallow on summits of ridges and mesas.
DRAINAGE AND PERMEABILITY: Excessively drained, negligible runoff, and rapid permeability.
USE AND VEGETATION: This series is used for rangeland. The present vegetation is Indian ricegrass, big sagebrush, blue grama, sand dropseed, and rubber rabbitbrush.
DISTRIBUTION AND EXTENT: West central, New Mexico; MLRA 35, LRR-D. This series is of small extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Phoenix, Arizona.
SERIES ESTABLISHED: McKinley County Area, New Mexico; McKinley County and Parts of Cibola and San Juan Counties, 2001.
