COMPETING SERIES: These are the Litle and Losmarios series. Litle soils have a paralithic contact at 20 to 40 inches. Losmarios soils have 10YR hues.
GEOGRAPHIC SETTING: Camino soils are on undulating plateaus and valley side slopes. They have slopes of 1 to 7 percent. The climate is semiarid. Mean annual precipitation is about 10 to 12 inches, and mean annual temperature is about 52 to 54 degrees F. Elevations are 5,700 to 6,600 feet. The frost-free period is 120 to 140 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Sandoval, and Sparank soils. Sandoval soils have paralithic contacts at less than 20 inches. Sparank soils are stratified soils on flood plains.
DRAINAGE AND PERMEABILITY: Well drained; medium runoff; slow permeability.
USE AND VEGETATION: Camino soils are used for livestock grazing. The present vegetation is alkali sacaton, western wheatgrass, and galleta.
DISTRIBUTION AND EXTENT: Northcentral New Mexico. Series is of small extent.
