Gray Wooded Soils of the Black Hills of South Dakota

Abstract The morphology, classification, and laboratory characteristics of the wooded soils of the Black Hills of South Dakota are reported. Field morphology studies involving parts of two summers tentatively established the classification of these soils in the Gray Wooded Soil Group. Paired profiles representing the central concept of the Gray Wooded group were sampled and laboratory characteristics determined. These soils resemble Gray Wooded soils reported for Canada, Montana, and the Northern Lake States. Additional paired profiles of giant or maximal Gray Wooded profiles and Gray Wooded intergrade profiles also were sampled and are characterized. A description of a pygmy or minimal Gray Wooded profile is described but was not sampled for analysis.
