CABINCOVE SERIES

The Cabincove series consists of moderately deep, well drained soils formed in colluvium and slope alluvium over residuum weathered from granitic rocks. The Cabincove soils are on mountain slopes of the Sierra Nevada Mountains. Slopes range from 10 to 80 percent. The mean annual precipitation is about 1025 mm and the mean annual air temperature is about 9 degrees C.

TAXONOMIC CLASS: Sandy, isotic, mesic Vitrandic Humixerepts

TYPICAL PEDON: Cabincove sandy loam on a southeast-facing (152 degree), 43 percent slope under mixed conifer and hardwood forest at an elevation of 1852 meters. (Colors are for dry soils unless otherwise noted. When described on April 20, 2015 the soil was slightly moist throughout.)

(3 to 15 cm thick)

Bw--14 to 30 cm; brown (10YR 5/3) gravelly loamy sand, very dark grayish brown (10YR 3/2) moist; 4 percent clay; weak medium subangular blocky structure; soft, very friable, nonsticky, nonplastic; common very fine, fine, medium, and coarse roots throughout; many very fine and fine and common medium irregular pores; 15 percent subrounded very strongly cemented granite fine gravel; NaF pH 9.0; slightly acid (pH 6.4); clear smooth boundary. (10 to 30 cm thick)

C--30 to 68 cm; pale brown (10YR 6/3) gravelly loamy sand, dark grayish brown (10YR 4/2) moist; 3 percent clay; weak fine subangular blocky structure; soft, very friable, nonsticky, nonplastic; common very fine, fine, medium, coarse, and very coarse roots throughout; common very fine, fine, and medium irregular pores; 25 percent subrounded strongly cemented granite fine gravel, 2 percent rounded moderately cemented granite paracobbles; NaF pH 8.5; slightly acid (pH 6.4); abrupt wavy boundary. (15 to 60 cm thick)

Cr--68 to 147 cm; moderately cemented granite bedrock, fractured at intervals of greater than 200 cm; few fine and common medium, coarse, and very coarse roots top of horizon.

TYPE LOCATION: Tulare County, California, on the Sequoia Lake trail; USGS 7.5 minute topographic quadrangle: General Grant Grove, California; WGS84 36.736754 latitude and -118.976235 longitude; UTM zone 11 4067490 meters N 323549 meters E NAD83.

RANGE IN CHARACTERISTICS:
Soil temperature: The mean annual soil temperature at 50 cm is 8 to 15 degrees C and the difference between mean summer and mean winter soil temperature is greater than 6 degrees C. The soils have a mesic temperature regime.

Soil moisture: The soils have a xeric soil moisture regime. The soil moisture control section is dry in all parts from about June to October (about 150 days).

Diagnostic Feature(s):

COMPETING SERIES: These are the Azalea, Generalgrant and Tharpslog soils. The Azalea soils are on convex shoulders and backslopes of mountain slopes and have a lithic contact between 50 and 100 cm. The Generalgrant soils are on concave footslopes of stream terraces and drainageways on mountain slopes and are moderately well drained. The Tharpslog soils are on broadly concave backslopes on mountain slopes and are somewhat excessively drained.

GEOGRAPHIC SETTING: The Cabincove soils are on backslopes of mountain slopes. Slopes range from 10 to 80 percent. These soils formed in colluvium and slope alluvium over residuum weathered from granite and granodiorite. Elevation is 970 to 2540 meters. The climate is Mediterranean with warm, dry summers and cool, moist winters. The mean annual precipitation is 725 to 1140 mm and the mean annual air temperature is 7 to 15 degrees C. The frost free season is 110 to 250 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Canyonview and Tharpslog soils. The Canyonview soils formed in colluvium on convex backslopes of steep mountain slopes and glacial valley walls, are greater than 150 cm to a bedrock contact, and have greater than 35 percent rock fragments in the particle-size control section. The Tharpslog soils are formed in residuum on footslopes and backslopes of broadly concave mountain slopes and are greater than 150 cm to a bedrock contact.

DRAINAGE AND PERMEABILITY: Well drained, high to very high saturated hydraulic conductivity. Saturated hydraulic conductivity of the bedrock is low to moderately low.

USE AND VEGETATION: This soil is used for recreation, wildlife habitat, and watershed. Vegetation is white fir, sugar pine, incense cedar, Jeffrey pine, black oak, greenleaf manzanita, and chinquapin.

DISTRIBUTION AND EXTENT: Sierra Nevada Mountains of California; MLRA 22A. These soils are of moderate extent.
