TYPE LOCATION: Chelan County, Washington; about 2 miles north of Peshastin; 300 feet east and 800 feet north of the southwest corner section 10, T.24N., R.18E.
RANGE IN CHARACTERISTICS: These soils are usually moist, but are dry in all parts between the depths of 8 to 24 inches for 75 to 90 consecutive days after the summer solstice. Mean annual soil temperature at a depth of 20 inches is 47 to 50 degrees F. The mollic epipedon is 10 to 20 inches thick. The solum is 36 to 44 inches thick. The particle-size control section averages 0 to 5 percent coarse fragments and 10 to 18 percent clay.
The A horizon has value of 4 or 5 dry, 2 or 3 moist, and chroma of 2 or 3 dry or moist.
The Bw horizon has value of 5 or 6 dry, 4 or 5 moist, and chroma of 3 or 4 dry or moist. It is loam or silt loam. Soil reaction is neutral or mildly alkaline.
The C horizon has value of 5 or 6 dry, 4 or 5 moist, and chroma of 2 to 4 dry or moist. It is loam or silt loam. Soil reaction is neutral or mildly alkaline.
COMPETING SERIES: These are the Ardening (T), Billyridge (T), Canderly, Catelli, Conconully, Crouch, Donavan, Fanal (T), Ginnis, Hellgate, Picard, Rebecca, Shangland, Spokane, Usk and Wind River series. Ardening soils are dry for 60 to 75 consecutive days and average 15 to 35 percent weathered schist fragments in the particle-size control section. Billyridge soils are dry for 60 to 75 consecutive days and average 5 to 25 percent rock fragments in the particle-size control section. Canderly and Crouch soils have a mean annual soil temperature of 54 to 56 degrees F. and both soils have sola thicker than 40 inches. Catelli, Ginnis, Shangland, Spokane, and Usk soils have a paralithic contact at 20 to 40 inches. Conconully soils are dry for 90 to 105 consecutive days and average 15 to 35 percent rock fragments in the particle-size control section. Donavan soils have 10 to 35 percent rock fragments in the particle-size control section. Fanal soils have mottles in the lower B and C horizons. Hellgate soils have 25 to 50 percent coarse and very coarse sand in the particle-size control section. Picard soils are very fine sandy loam and fine sandy loam in the Bw horizon. Rebecca soils average 15 to 35 percent rock fragments in the particle-size control section. Wind River soils have a mean annual soil temperature of 50 to 54 degrees F. and solum thickness of 15 to 25 inches.
GEOGRAPHIC SETTING: Burrant soils are on terraces. These soils formed in alluvium and colluvium from sandstone mixed with loess. Slopes are 3 to 25 percent. Elevations range from 1,100 to 1,600 feet. The climate is characterized by warm, dry summers and cool, moist winters. The average annual precipitation is 18 to 24 inches, the mean January temperature is about 25 degrees F, the mean July temperature is about 71 degrees F, and the mean annual air temperature is 45 to 48 degrees F. The frost-free season is 105 to 140 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Burch, Cle Elum and Varelum soils. Burch soils are on terraces and are usually dry, and have a mean annual soil temperature of 50 to 55 degrees F. Cle Elum soils are on foothills and mountainsides and have bedrock at 20 to 40 inches. Varelum soils are on foothills and mountainsides and have 20 to 35 percent clay in the particle-size control section.
DRAINAGE AND PERMEABILITY: Well drained; slow or medium runoff; moderate permeability.
USE AND VEGETATION: Irrigated orchards, irrigated hay and pasture, livestock grazing, woodland, and wildlife habitat. Native vegetation is ponderosa pine and Douglas-fir, with an understory of pinegrass, common snowberry, arrowleaf balsamroot, and creambush oceanspray.
DISTRIBUTION AND EXTENT: Central Washington. The series is of small extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Portland, Oregon
SERIES PROPOSED: Cashmere Mt. Soil Survey, Chelan County, Washington, 1989.
REMARKS: Diagnostic horizons and features recognized in this soil are a mollic epipedon from the surface to 16 inches, and a cambic horizon from 16 to 42 inches. This soil was previously named as Burch Variant, and it is suspected to also occur in the Chelan County Area soil survey.
