TYPE LOCATION: Marquette County, Michigan: about 200 feet south and 730 feet east of the northwest corner of Sec. 31, T. 47 N., R. 29 W. USGS topo quadrangle Republic; lat. 46 degrees 26 minutes 4 seconds N., and long. 87 degrees 59 minutes 18 seconds W.
RANGE IN CHARACTERISTICS: (Unless otherwise stated the depth ranges in this paragraph are from the mineral soil surface.) Thickness of the silty or loamy eolian mantle ranges from 20 to 35 inches. Solum thickness ranges from 15 to 30 inches. Gravel content ranges from 0 to 15 percent in the loamy mantle and from 0 to 60 percent in the sandy lower horizons. Cobbles range from 0 to 5 percent in the loamy mantle and from 0 to 10 percent in the sandy lower horizons. Stones range from 0 to 2 percent throughout.
Some pedons have an O horizon with hue of 5YR or 7.5YR, value of 2.5 or 3, and chroma of 1 or 2.
The A horizon has hue of 5YR to 10YR, value of 2 to 3, and chroma of 1 or 2. The E horizon has hue of 5YR or 7.5YR, value of 4 or 5, and chroma of 1 or 2. The A and E horizons are silt loam, very fine sandy loam, fine sandy loam, or the gravelly analogues of these textures. Reaction of the A and E horizons ranges from very strongly acid to moderately acid.
The Bs1 horizon has hue of 5YR or 7.5YR, value of 3 to 5, and chroma of 3 or 4. It is silt loam, very fine sandy loam, fine sandy loam, or the gravelly analogues of these textures. Reaction ranges from strongly acid to moderately acid.
The Bs2 horizon has hue of 5YR or 7.5YR, value of 3 to 5, and chroma of 4 to 6. It is silt loam, very fine sandy loam, or fine sandy loam. Reaction ranges from strongly acid to moderately acid.
The 2BC horizon has hue of 7.5YR or 10YR, value of 4 or 5, and chroma of 4 to 6. It is sand, loamy sand, loamy coarse sand, or the gravelly or very gravelly analogues of these textures.
The 2C horizons have hue of 7.5YR or 10YR, value of 4 to 6, and chroma of 3 to 6. They are sand, coarse sand, or the gravelly, very gravelly, or cobbly analogues of these textures. Stratification is common. Reaction is moderately acid to slightly acid.
COMPETING SERIES: There are no other series in the family.
GEOGRAPHIC SETTING: Chabeneau soils are on outwash plains, eskers and stream terraces. Slope ranges from 0 to 18 percent. Mean annual precipitation ranges from 32 to 38 inches. Mean annual temperature ranges from 40 to 43 degrees F. The frost free period ranges from 100 to 130 days per year. Elevations range from 800 to 1800 feet.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the well drained Keewaydin and Sundog soils, the somewhat poorly drained Channing soils, the poorly drained Minocqua and Witbeck soils, and the very poorly drained Carbondale and Tawas soils.
DRAINAGE AND PERMEABILITY: Moderately well drained. Depth to the apparent seasonal high water table ranges from 2.0 to 3.0 feet at some time during the period from November to May. The soil is saturated with water within 40 inches of the mineral surface for 1 month or more per year in 6 or more out of 10 years. Surface runoff is slow. Permeability is moderate in the upper part very rapid in the lower part of the soil.
USE AND VEGETATION: Most areas of this soil are forested. Common trees are red maple, quaking aspen, white pine, paper birch, balsam fir, black spruce, and white spruce.
DISTRIBUTION AND EXTENT: Central and western Upper Peninsula of Michigan, and possibly adjacent areas of northern Wisconsin. The series is of moderate extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: St. Paul, Minnesota.
SERIES ESTABLISHED: Marquette County, Michigan, 1998. The source of the name is a lake in the county.
REMARKS: Diagnostic horizons and features recognized is this soil are: a.bic horizon - the zone from 2 to 5 inches, (E horizon); spodic horizon - the zone from 5 to 22 inches, (Bs1 and Bs2 horizons). Oxyaquic subgroup - the soil is saturated with water in one or more layers with 100 cm (40 inches) of the mineral surface for 1 month or more per year in 6 or more out of 10 years. Lithologic discontinuity from loamy eolian material to sandy outwash at 30 inches.
