COMPETING SERIES: These are the Graystone, Greenhope, Guy, Humbarsprings, Laird, and Sidney series. The Graystone, Greenhope, Guy, Humbarsprings, and Laird soil all have more than 10 percent calcium carbonate equivalent. The Sidney soils are deep to a paralithic contact.
GEOGRAPHIC SETTING: Junebee soils are on toeslopes of erosional fan remnants. They formed in alluvium derived from Tertiary granitic sandstone, fanglomerate, and mudstone. Slopes are 5 to 15 percent. Elevation ranges from 6,100 to 7,800 feet. The mean annual precipitation is 13 to 15 inches with about 45 percent falling as rain from high-intensity convective thunderstorms between July and September. The mean annual air temperature is 47 to 50 degrees F. The frost-free period is 140 to 160 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Buckhorse, Encantado, and Levante soils. Buckhorse soils have thin mollic epipedons and occur on adjacent non-wooded toeslopes. Encantado soils are sandy-skeletal, have calcic horizons, and occur on shoulders and backslopes of eroded fan remnants. Levante soils are sandy and occur on narrow flood plains of arroyos.
DRAINAGE AND PERMEABILITY: Somewhat excessively drained; low surface runoff; moderately rapid permeability.
USE AND VEGETATION: Junebee soils are used for urban development, livestock grazing, and recreation. The historic climax vegetation is blue grama, Indian ricegrass, sand dropseed, other perennial forbs, galleta. The ecological site is Deep Sand(R036XB115NM).
DISTRIBUTION AND EXTENT: Junebee soils are of small extent on the southeastern Espanola Basin part of the Basin and Range province in northcentral New Mexico. The MLRA is 36.
