TYPE LOCATION: Barron County, Wisconsin; about 4 1/2 miles southeast of Chetek; 400 feet north and 1760 feet west of the southeast corner of section 16, T. 32 N., R. 10 W.
RANGE IN CHARACTERISTICS: Thickness of the loamy mantle and depth to sandy residuum, ranges from 20 to 39 inches. Depth to a paralithic contact with sandstone ranges from 20 to 40 inches. Except for thin (less than 5 inch) transition horizons above the sandy 2B horizon, the coarse-loamy mantle has less than 50 percent fine or coarser sand and averages 7 to 17 percent clay. Volume of gravel ranges from 0 to 15 percent in the loamy mantle. Volume of sandstone channers ranges from 0 to 15 percent in the sandy residuum. Typically reaction ranges from very strongly acid to moderately acid throughout the pedon but it ranges to neutral in the upper part of the solum, where the soil is limed. Redox accumulations are typically throughout the soil below the A or Ap horizon. Redox depletions with chroma of 2 or less are within the upper 10 inches of the argillic horizon or higher. Saturation occurs in the upper 10 inches of the argillic horizon at some time in most years.
The Ap horizon has value of 3 or 4 and chroma of 2 or 3. Uncultivated pedons have an A horizon with hue of 10YR, value of 2 or 3, and chroma of 1 or 2.
The E horizon has value of 4 to 6 and chroma of 2 or 3. Colors of 4/3 or 5/3 have value dry of 7 or more. The E horizon is silt loam, loam, sandy loam, fine sandy loam, or very fine sandy loam.
Siouxcreek soils have a glossic horizon (E/B or B/E horizons, or both). The E part has color and texture like the E horizon described above. The Bt part has hue of 7.5YR or 10YR, value of 4 or 5, and chroma of 4 to 6. It is silt loam, loam, sandy loam, or fine sandy loam.
The Bt horizon has color and texture like the Bt part described above. Some pedons with a B/E horizon do not have a Bt horizon.
The 2BC or 2Bt horizon has hue of 7.5YR, 10YR, or 2.5Y; value of 4 to 7; and chroma of 4 to 6. It is loamy sand, loamy fine sand, sand, or fine sand.
COMPETING SERIES: This is the Ossmer series. A similar soil is the Arland series. Ossmer soils do not have a paralithic contact within the series control section. Arland soils do not have redox features or a water table.
GEOGRAPHIC SETTING: Siouxcreek soils are in broad drainageways and depressions underlain by sandstone on glaciated uplands. Slopes range from 0 to 3 percent. These soils formed dominantly in silty or loamy alluvium or in silty or loamy alluvium and till over sandy residuum from the underlying weakly cemented sandstone. Mean annual precipitation ranges from 28 to 33 inches. Mean annual temperature ranges from 39 to 45 degrees F. The frost free period ranges from about 120 to 135 days. Elevation ranges from 800 to 1950 feet.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Arland and Hayriver soils. The well drained Arland soils are nearby on higher landscape positions. The well drained Hayriver soils are on adjacent side slopes at lower elevations where geologic erosion has removed the loamy glacial deposits and the soil is formed in loamy residuum from sandstone.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained. Surface runoff is slow. Permeability is moderate in the loamy solum and moderately rapid or rapid in the sandy residuum. These soils have an perched seasonal water table at a depth of 1 to 2.5 feet at some time during the period from September to June in most years.
USE AND VEGETATION: Most areas have been cleared and are used for pastureland or cropland. Common crops are corn, small grain, and hay. The native vegetation is mixed hardwood forest. Common trees are red maple, silver maple, white ash, green ash, quaking aspen, and bigtooth aspen.
DISTRIBUTION AND EXTENT: Northwestern Wisconsin. These soils are of small extent.
