TYPE LOCATION: Lake County, California; 1 mile east of Highway 53 on Davis Street east of Clear Lake Highlands, about 10 feet north of the roadway; 2,000 feet east and 50 feet north of the southwest corner of sec. 23, T. 13 N., R. 7 W., MDB&M. Lower Lake Quadrangle.
RANGE IN CHARACTERISTICS: The thickness of the solum ranges from 30 to 50 inches and the depth of the soil is more than 60 inches. The mean annual soil temperature ranges from 59 degrees to 63 degrees F. The soil between the depths of 7 to 29 inches is dry in all parts from July 1 to October 15, and is moist in all parts from January 1 to April 30. Soil reaction ranges from slightly acid to neutral throughout. Coarse and very coarse sand is more than 15 percent throughout. Base saturation varies from 75 to 95 percent throughout. Variegated colors from weathered rock fragments are in the lower argillic and C horizons in many pedons.
The A horizon dry color is 10YR 5/4, 4/4, 4/3, or 3/3. Moist colors are 10YR 4/3, 3/2, or 2/2. Where moist color values are 3 or 2, the A1 horizon is less than 4 inches thick. It is sandy clay loam or loam with 15 to 35 percent rock fragments. Organic carbon varies from 1 to 2 percent.
The Bt horizon dry color is 7.5YR 7/8, 5/4 or 4/4. Moist colors are 10YR 4/4, 4/3; 7.5YR 5/4, 4/4, 3/4. It is clay loam or sandy clay loam, clay or sandy clay and ranges from 25 to 55 percent clay content. Rock fragments range from 35 to 60 percent. The particle-size control section averages 35 to 45 percent clay and 35 to 50 percent rock fragments.
The 2C horizon dry color is 10YR 5/4; 7.5YR 7/8, 6/4, or 5/4. Moist colors are 10YR 4/4; 7.5YR 5/4 or 4/4. It is sandy clay loam and clay loam with 50 to 60 percent rock fragments. Clay content typically varies from 20 to 30 percent.
COMPETING SERIES: These are the Phipps and Yorba series in other families. Phipps soil are fine. Yorba soils are loamy-skeletal.
GEOGRAPHIC SETTING: Bally soils are on uplifted dissected hills in the Cache formation. Slopes vary from 2 to 50 percent. The soils formed from old loosely consolidated stratified sandy and gravelly alluvium. Elevations are 1,100 to 2,500 feet. The climate is subhumid with cool wet winters and hot dry summers. Mean July temperature is 68 degrees F; mean January temperature is 41 degrees F; and mean annual temperature is 55 degrees to 59 degrees F. Mean annual precipitation is 25 to 35 inches. Frost-free season is 160 to 200 days.
GEOGRAPHICALLY ASSOCIATED SOILS: This is the competing Phipps and the Manzanita, and Redvine series. Manzanita soils are fine-loamy. Redvine soils are fine. Both soils occur on terraces.
DRAINAGE AND PERMEABILITY: Well drained; runoff is medium on gentle slopes and rapid or very rapid on steeper slopes; slow permeability.
USE AND VEGETATION: Used for wildlife and watershed, livestock grazing and homesite development. Native vegetation is mainly chamise and buckbrush ceanothus. Wild oats, soft chess, other annual grasses and blue oak are found on gentler slopes.
DISTRIBUTION AND EXTENT: Lake County, California; east of Clear Lake Highlands. The series is not extensive.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Davis, California
