(6 to 15 inches thick)
C--20 to 48 inches; reddish yellow (7.5YR 6/6) sandy loam, brown (7.5YR 5/4) moist; massive; slightly hard; friable, nonsticky, nonplastic; few fine and medium roots; few thin clay films in bridges; strongly acid (pH 5.5). (12 to 24 inches thick)

TYPE LOCATION: Shasta County, California, 1.4 miles south of Shasta and 1900 feet west and 250 feet north of the SE corner Sec. 36, T.32N, R.6W.
RANGE IN CHARACTERISTICS: Solum thickness is 12 to 29 inches to the bottom of the B2 horizon and mean annual soil temperature ranges from 61 to 63 degrees F. The A horizon colors are grayish brown and brown to light yellowish brown and reddish yellow in 10YR and 7.5YR hues and have values of 5 and 6 dry and 4 moist. Chromas are 3 and 4 dry and 2 to 4 moist. Texture ranges from sandy loam to cobbly sandy loam and reaction from strongly acid to medium acid. The B2 horizon colors are very pale brown or pink, light brown and reddish yellow in 10YR and 7.5YR hues with values of 6 and 7 and chromas of 4 and 6 dry. Colors moist are brown and strong brown with values of 5 and 6 and chromas of 4 and 6. Texture ranges from sandy loam to heavy loam and reaction from very strongly acid to strongly acid.
COMPETING SERIES: These include the Auberry, Behemotosh, Chawanakee, Diamond Springs and Shaver series. The Auberry soils have slightly acid A horizons and brown Bt horizons. The Behemotosh soils have medium acid, very cobbly light clay loam Bt horizons. The Chawanakee soils lack B2 horizons and have very coarse sandy loam textures. The Diamond Springs soils have reddish yellow and yellowish red (moist) heavy sandy loam very strongly acid Bt horizons. The Shaver soils have 0 horizons and an umbric epipedon.
GEOGRAPHIC SETTING: The Kanaka soils occur on gently sloping to very steep uplands under shrubs, oaks and ponderosa pine. They are underlain br granitic or metavolcanic rocks. Elevations range from 500 to 1,000 feet in a moist subhumid climate with a mean annual rainfall of 45 to 60 inches, with hot dry summers and cool moist winters. Mean annual temperature is about 62 degrees F., average January temperature about 43 degrees F., and average July temperature about 81 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: Kanaka soils occur in the same general area as the Auberry, Auburn, Behemotosh, Chawanakee, Goulding and Diamond Springs soils.
DRAINAGE AND PERMEABILITY: Somewhat excessively drained, moderately rapid permeability; medium to rapid runoff. Erosion hazard is high.
USE AND VEGETATION: Watershed and range use. Natural vegetation is manzanita, toyon, oak, digger pine and knobcone pine.
DISTRIBUTION AND EXTENT: Shasta County, California, where they are inextensive.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Davis, California
SERIES PROPOSED: Shasta County, California, 1965. Name from Kanaka Peak, Shasta County.
REMARKS: The Kanaka series was formerly classified in the Regosol group. The soils have ochric epipedons and cambic horizons.
