TYPE LOCATION: Bryan County, Oklahoma; about 1-1/2 miles north of Bennington; 1320 feet west and 1890 feet south of the northeast corner of sec. 22, T. 6 S., R. 12 E.
RANGE IN CHARACTERISTICS: Solum thickness ranges from 60 to more than 80 inches.
The A1 horizon has hue of 7.5YR or 10YR, value of 3 or 4, and chroma of 2 or 3. It is medium acid or strongly acid except where limed.
The A2 horizon has hue of 7.5YR or 10YR, value of 4 to 6, and chroma of 2 to 6. It is medium acid or strongly acid except where limed.
The B21t horizon has hue of 2.5YR, 5YR, or 7.5YR, value of 4 to 6, and chroma of 4 to 8. It has mottles of chroma 2 or within 30 inches of the soil surface. This horizon is clay loam, silty clay loam, silty clay, or clay and is strongly acid or very strongly acid.
The B22t, B23t, B24t, and B3 horizons have textures and colors like the B21t horizon but have brownish, yellowish, or grayish mottles. These horizons are medium acid through very strongly acid.
COMPETING SERIES: These are the Counts series. Counts soils have hues no redder than 10YR throughout.
GEOGRAPHIC SETTING: These are nearly level through moderately steep soils on uplands. Slopes range from 0 to 15 percent. These soils formed in loamy and clayey sediments. Average annual precipitation ranges from 40 to 50 inches; mean annual temperature ranges from 62 degrees to 72 degrees F.; Thornthwaite P-E indices range from 64 to 80.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bernow and Hamden series. Bernow soils have a fine-loamy control section and Hamden soils have a fine-silty control section.
DRAINAGE AND PERMEABILITY: Moderately well drained; slow to rapid runoff; very slow permeability.
USE AND VEGETATION: Used mainly as pasture and range. Minor areas are cultivated to wheat, grain sorghum, soybeans, and peanuts. Native vegetation is mainly oak with an understory of grasses.
DISTRIBUTION AND EXTENT: Southeastern Oklahoma and possibly Arkansas. These soils are moderately extensive.

REMARKS: Soil Interpretation Record: Series OK0121
The soils would have been classified in the Red-Yellow Podzolic great soil group. These soils were mapped as the Boswell series in previous soil surveys.
