COMPETING SERIES: This is the Medici and Stacher (T) series. Medici soils have 15 to 30 percent glass in the 0.2 to 2mm fraction. Stacher soils have 20 to 25 percent clay and a base saturation of 3 to 9 percent in the lower part of the control section and have a combined A and Bw thickness of more than 60 inches.
GEOGRAPHIC SETTING: Carberry soils are on lava plateaus and hills. Slopes are 2 to 50 percent. These soils formed in tephra. Elevation is 3,200 to 5,800 feet. The climate is subhumid with warm dry summers and cold moist winters. Mean annual precipitation is 35 to 45 inches. Snowfall is 60 to 96 inches. The mean annual temperature is 39 to 41 degrees F. The mean January temperature is about 28 degrees F. The mean July temperature is about 58 degrees F. Frost-free season is 50 to 80 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Depner, Goulder, and competing Stacher (T) soils. Depner soils are on lava plateaus and hills, have andic properties from 0 to 40 inches, have mesic temperature regime and have 20 to 25 percent clay in the control section. Goulder soils are on mountains, have argillic horizons, have andic properties from 0 to 17 inches, and are greater than 60 inches deep. Stacher soils are on mountains, have 18 to 25 percent clay in the control section, have andic properties from 0 to 14 inches, and are greater than 60 inches deep to a paralithic contact.
DRAINAGE AND PERMEABILITY: Well drained; slow to rapid runoff; moderately rapid permeability.
USE AND VEGETATION: This soil is used for timber production. The natural vegetation is White fir, sugar pine, ponderosa pine, incense cedar, Douglas fir, greenleaf manzanita, Sierra chinkapin, western serviceberry, Nutall willow, snowbrush ceonothus, and Bracken fern.
DISTRIBUTION AND EXTENT: Northeastern California. The soils are not extensive. MLRA is 22.
