Bw--50 to 57 inches; dark yellowish brown (10YR 3/4) silt loam; weak coarse subangular blocky structure; friable; neutral; gradual smooth boundary. (4 to 20 inches thick)

TYPE LOCATION: Pepin County, Wisconsin; about 3/4 miles north of Pepin; 1000 feet north and 1300 feet east of the southwest corner of sec. 24, T. 23 N., R. 15 W.; Latitude: 44 degrees 27 minutes 21 seconds N; Longitude: 92 degrees 9 minutes 3 seconds W
RANGE IN CHARACTERISTICS: Thickness of the silty alluvium and the depth to sandy outwash ranges from 40 to 80 inches. The mollic epipedon is 24 or more inches thick. Weighted average total sand content ranges from 5 to 30 percent in the silty alluvium but the weighted average content of fine sand or coarser is less than 15 percent. Rock fragments are typically absent in the silty alluvium but volume of sandstone channers ranges from 0 to 15 percent. Volume of gravel ranges from 0 to 35 percent and volume of cobbles ranges from 0 to 5 percent in the sandy outwash.
The Ap and A horizons have hue of 10YR, value of 2 or 3, and chroma of 1 to 3. Surface texture is silt loam. Reaction ranges from medium acid to slightly alkaline.
The Bw horizon has hue of 7.5YR or 10YR, value of 3 to 5 and chroma of 3 to 6. It is silt loam or loam. Reaction ranges from medium acid to neutral.
The 2C horizon has hue of 7.5YR or 10YR, value of 5 to 7, and chroma of 3 to 6, or it is multicolored. It is coarse sand, sand, or the gravelly analogs. Reaction ranges from strongly acid to slightly acid.
COMPETING SERIES: There are no competing series. Similar soils are the Huntsville, Judson, Lindstrom, and Worthen series. All these soils are fine-silty.
GEOGRAPHIC SETTING: Boguscreek soils are on drainageways on valley trains near loess mantled hills. Slopes range from 0 to 3 percent. Mean annual precipitation ranges from 28 to 33 inches. Mean annual air temperature ranges from 46 to 51 degrees F. Frost free period ranges from about 135 to 160 days. Elevation ranges from 600 to 900 feet.
GEOGRAPHICALLY ASSOCIATED SOILS: Near the Type Location these include the Chaseburg, Chelsea, Finchford, Plainfield, and Rasset series. The well drained Chaseburg soils are higher in the landscape on toeslopes of hills. Chaseburg soils formed in lighter colored silty alluvium and are not underlain by sandy outwash within 80 inches. The excessively drained Chelsea soil formed on dunes in more than 80 inches of fine sand with lamellae. The somewhat excessively drained Rasset soils formed in 20 to 40 inches of loamy alluvium underlain by sandy outwash to a depth of 60 inches or more. The excessively drained Finchford and Plainfield soils formed in sandy outwash more than 60 inches thick. Near the Type Location, the Finchford soils are on treads of valley trains and the Plainfield soils are on risers of valley trains.
DRAINAGE AND PERMEABILITY: Well drained. Permeability is moderate in the silty alluvium and rapid or very rapid in the sandy outwash. Boguscreek soils are subject to occasional, very brief flooding at some time during the period of March to July.
USE AND VEGETATION: Most areas of Boguscreek soils are used for cropland. Corn, soybeans, small grains, and hay are the principal crops. Native vegetation is deciduous forest. Common trees are northern red oak, sugar maple, and American basswood.
DISTRIBUTION AND EXTENT: West-central Wisconsin. K91 inclusion in M105. This soil is of small extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: St. Paul, Minnesota
SERIES ESTABLISHED: Pepin County, Wisconsin, 1998. Source of the name is a nearby creek.
REMARKS: Prior to 1996 in Wisconsin, Boguscreek soils were mapped as the Richwood and Judson series.
Diagnostic horizons and other features recognized in this pedon are: mollic epipedon - 0 to 50 inches (Ap, A1, A2, A3, A4); cambic horizon - 50 to 57 inches (Bw horizon); cumulic feature - mollic epipedon 24 or more inches thick.
