TYPE LOCATION: Sanborn County, South Dakota; 1 1/2 miles north and 1 1/2 miles west of Forestburg; 2,300 feet north and 1,600 feet east of the southwest corner of sec. 27, T. 107 N., R. 61 W. USGS Topographical Quadrangle - Forestburg SW, S. Dak; Latitude: 44 degrees, 2 minutes, 48 seconds N; Longitude: 98 degrees, 8 minutes, 46 seconds W.
RANGE IN CHARACTERISTICS: Depth to till ranges from 20 to 40 inches. Thickness of the mollic epipedon ranges from 10 to 16 inches and corresponds to the thickness of the A horizon. Depth to carbonate typically corresponds to the depth to the till. The C horizon above the till, where it occurs, is calcareous in some pedons.
The A horizon has hue of 10YR, value of 3 to 5 and 2 or 3 moist, and chroma of 1 or 2. It typically is loamy fine sand or loamy sand, but is sandy loam or fine sand in some pedons. It is neutral or slightly alkaline. It has few or common, faint to distinct redox features and oxide stains.
The Bw horizon has hue of 10YR or 2.5Y, value of 4 to 6 and 2 to 4 moist, and chroma of 1 to 3 It is loamy fine sand, loamy sand or fine sand. It has common or many redox features. It is neutral or slightly alkaline. Some pedons have an AC horizon up to 10 inches thick with similar properties.
The C horizon, where present, has hue of 2.5Y or 10YR, value of 4 to 6 and 3 or 4 moist, and chroma of 2 to 4. It is loamy fine sand, loamy sand, or fine sand. Redox features range from common to many, fine to coarse, and faint to prominent. It is neutral or slightly alkaline.
The 2Bk and 2C horizons have hue of 2.5Y or 5Y value of 5 to 7 and 4 to 6 moist, and chroma of 2 to 4. They typically are loam or clay loam, but are silt loam or silty clay loam containing thin lenses of coarser textures in some pedons. Few to many, fine or medium accumulations of carbonate are in the upper part. Redox features are distinct or prominent. Common fine nests of gypsum are in the lower part in some pedons. They are slightly alkaline or moderately alkaline.
COMPETING SERIES: These are no competing series in the same family.
GEOGRAPHIC SETTING: Shue soils are in shallow depressions. Slopes are plane or concave and gradients are 1 percent or less. The soils formed in sandy eolian material overlying till. The mean annual air temperature ranges from 45 to 50 degrees F, and the mean annual precipitation ranges from 18 to 21 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Blendon, Carthage, Doger, Els, Elsmere, Fedora, Forestburg, Ipage and Loup soils. The Blendon, Carthage, Doger, Forestburg and Ipage soils are on higher positions in nearby landscapes and are drier. Els and Elsmere soils do not have contrasting substrata above a depth of 40 inches and are on slightly higher positions on the landscape. Fedora soils have a calcic horizon and are on the edges of swales or shallow depressions. Loup soils are sandy throughout.
DRAINAGE AND PERMEABILITY: Poorly drained. Runoff is ponded. Permeability is rapid in the sandy mantle and moderately slow in the underlying till. A perched, seasonal water table is at depths of 1 foot above the surface to 1 foot below the surface at some time during the period of March through July in most years.
USE AND VEGETATION: Corn is the principal crops in cultivated areas. Native vegetation includes prairie cordgrass and sloughsedge.
DISTRIBUTION AND EXTENT: East central South Dakota. The series is moderately extensive.

REMARKS: Diagnostic horizons and features recognized in this pedon are: mollic epipedon - the zone from the surface of the soil to a depth of 11 inches (A horizon).
