TYPE LOCATION: Rio Arriba County, New Mexico; 0.6 mile south and 6 miles west of Cebolla, New Mexico; 1,198 feet north and 1,407 feet west of the SE corner of Sec. 33, T. 27 N., R. 3 E.; 106 degrees, 37 minutes, 16 seconds west longitude; 36 degrees, 31 minutes, 35 seconds north latitude.
RANGE IN CHARACTERISTICS:
Soil Moisture: Intermittently moist in some part of the soil moisture control section December through April and July through October. The soil is driest during May and June.

COMPETING SERIES: This is the Berthoud(OK) series. Berthoud soils have mean annual temperatures of 54 to 57 degrees F. and are typically moist in early spring.
GEOGRAPHIC SETTING: Teromote soils are on knolls, valley and valley sides. Slopes range from 2 to 8 percent. Elevations are 7,100 to 7,400 feet. The soils formed in alluvium from shale. Mean annual precipitation is 12 to 17 inches. Mean annual temperature is 45 to 48 degrees F., and the frost-free period is about 100 to 115 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Ruson and Berryman soils. Ruson soils lack a cambic horizon. Berryman soils have carbonatic mineralogy.
DRAINAGE AND PERMEABILITY: Well drained; medium runoff; moderately slow permeability.
USE AND VEGETATION: Teromote soils are used for grazing livestock. The vegetation is western wheatgrass, bottlebrush squirreltail, Indian ricegrass, galleta, and blue grama.
DISTRIBUTION AND EXTENT: Well drained; medium runoff; moderately slow permeability.
