TYPE LOCATION: Okanogan County, Washington; 1,518 feet north and 264 feet east of the southwest corner of section 29, T.29N., R.23E. W. M.
RANGE IN CHARACTERISTICS: The mean annual soil temperature is 47 to 54 F. These soils are usually moist but are dry for 90 to 105 consecutive days following the summer solstice. The upper 7 to 14 inches of this soil has an estimated moist bulk densigy 1.00 to 1.50 g/cc, volcanic glass content of 5 to 30 percent, acid-oxalate extractable aluminum plus one-half of the acid-oxalate extractable iron of 0.4 to 1.0 percent, 15-bar water retention of 5 to 10 percent for air dried samples. Rock fragments in the particle-size control section average 35 to 60 percent. The mollic epipedon is 10 to 18 inches thick. Depth to bedrock is 40 to more than 60 inches.
The A horizons have hue of 10YR or 2.5Y, value of 4 or 5 dry, 2 or 3 moist, and chroma of 1 to 3 dry or moist.
The 2Bw horizons have hue of 10YR or 2.5Y, value of 5 to 7 dry, 3 to 5 moist, and chroma of 2 to 4 dry or moist. It is very gravelly sandy loam, very gravelly coarse sandy loam, very cobbly sandy loam, or very cobbly coarse sandy loam.
The 2C horizon has hue of 10YR or 2.5Y, value of 5 to 7 dry, 4 or 5 moist, and chroma of 2 to 4 dry or moist. It is very gravelly sandy loam, very gravelly coarse sandy loam, very cobbly sandy loam, very cobbly loamy sand, very cobbly loamy fine sand, very cobbly coarse sandy loam, very gravelly loamy sand.
COMPETING SERIES: This is the Raisio series. Raisio soils are 20 to 40 inches to a lithic contact.
GEOGRAPHIC SETTING: Wagberg soils are on back slopes and toe slopes of hills and on moraines. They formed in glacial till with minor amounts of volcanic ash and loess in the surface. Slopes are 0 to 90 percent. Elevation is 1,200 to 4,900 feet. Climate is characterized by hot, dry summers and mild, moist winters, average annual precipitation is 12 to 18 inches; average annual temperature is 45 to 52 F.; and the frost free season is 100 to 165 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Brief, Conconully, Domkey, Kartar and Thowson soils. Brief soils are on alluvial fans and terraces and are 15 to 35 percent rock fragments in the particle-size control section and have a base saturation of more than 75 percent in the upper 30 inches. Conconully soils are on foothills and are coarse-loamy in the particle-size control section. Domkey soil are on mountainsides and are dominated by volcanic ash and pumice in the upper part of the control section, are dry for 75 to 90 consecutive days following the summer solstice and have a frigid soil temperature regime. Kartar soils are on outwash terraces and are dry for 75 to 90 consecutive days, are coarse-loamy in the particle-size control section, and lack a mollic epipedon. Thowson soils are on mountainsides and are dry for 75 to 90 consecutive days following the summer solstice and are dominated by volcanic ash and pumice in the particle-size control section.
DRAINAGE AND PERMEABILITY: Well drained, medium or rapid runoff; moderately rapid permeability.
USE AND VEGETATION: Livestock, grazing, dryland crop production and wildlife habitat. Native vegetation is antelope bitterbrush, bluebunch wheatgrass, Idaho fescue, tall green rabbitbrush, arrowleaf balsamroot, saskatoon serviceberry, common yarrow, currant, threetip sagebrush, prairie junegrass, and scattered ponderosa pine.
DISTRIBUTION AND EXTENT: North-central Washington. The series is of small extent.

SERIES ESTABLISHED: Okanogan County, Washington, 1995. Cashmere Mountain Soil Survey.
REMARKS: Diagnostic horizons and features recognized in this pedon are a mollic epipedon from the surface to 13 inches, a cambic horizon from 13 to 53 inches. Rock fragments in the 10 to 40 inch control section average 43 percent. The base saturation (by sum) is estimated to less than 75 percent in parts of the upper 30 inches.
