TYPE LOCATION: Wood County, West Virginia; 225 yards south of Belleville, 450 yards west of State Route No. 2
RANGE IN CHARACTERISTICS: Solum thickness is commonly 40 to 60 inches but ranges to 70 inches. Thickness of the mollic epipedon is commonly 10 to 14 iches but ranges to 24 inches. Unlimed soils range from moderately acid to mildly alkaline throughout the profile. Rock fragments are commonly less than 1 percent but range to 3 percent by volume in the solum. Rock fragments of gravel or cobbles range from 0 to 30 percent in the C horizon. Mica flakes are common in many pedons.
The A or Ap horizon has hue of 10YR or 7.5YR, value of 2 or 3, and chroma of 1, 2, or 3. It is dominantly silt loam, but the range includes silty clay loam and loam.
The AB or BA horizon, where present, has hue of 10YR or 7.5YR, value of 4 or 5, and chroma of 2 or 3 in ped interiors. Ped surface colors are similar to the matrix colors of the A or Ap horizon.
The Bw horizon has hue of 10YR or 7.5YR, value of 4, and chroma of 2, or value of 4 or 5, and chroma of 3 or 4. Ped coatings commonly have value of 3, but range from 2 through 4. The Bw horizon is silt loam or silty clay loam. Clay content averages less than 30 percent.
The C horizon has colors similar to those of the Bw horizon. The C horizon commonly contains more sand than the Bw horizon and is stratified. Texture of the fine-earth fraction includes silt loam, fine sandy loam, loam, fine sand, silty clay loam, and sandy clay loam.
COMPETING SERIES: These are the Armiesburg and Omadi series in the same family and the Allison, Ashton, Boonesboro, Chagrin, Eudora, Huntsville, Moshannon, Nolin, Ross, and Rossburg series in other families. Armiesburg soils contain more than 30 percent clay in the Bw horizon. Omadi soils contain free carbonates and have solum thickness of less than 20 inches. Allison, Huntsville, and Ross soils have mollic epipedons that are more than 24 inches thick. The Ashton soils have an argillic horizon. Boonesboro soils have bedrock at a depth of less than 40 inches. Chagrin, Moshannon, and Nolin soils do not have amollic epipedon. Eudora soils contain less than 18 percent clay in the particle size control section. Rossburg soils are fine-loamy.
GEOGRAPHIC SETTING: Huntington soils are on flood plains. Slope gradients generally range from about 0 to 5 percent, but slopes ranging to 15 percent are common near large streams. Huntington soils formed in alluvium washed from soils formed in shale, sandstone, and limestone. Mean annual precipitation ranges from 35 to 55 inches, and mean annual air temperature ranges from 47 to 59 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Allegheny, Ashton, Chagrin, Dunning, Kanawha, Lindside, Melvin, Monongahela, Newark, Sciotoville, and Wheeling soils. The Allegheny, Monongahela. Sciotoville, and Wheeling soils have argillic horizons and are on stream terraces. Ashton and Kanawha soils are well drained and are on low stream terraces on high flood plains. The Chagrin, Dunning, Lindside, Melvin, and Newark soils are on flood plains. Chagrin soils are well drained; Lindside soils are moderately well drained; Newark soils are somewhat poorly drained; and Melvin and Dunning soils are poorly drained.
DRAINAGE AND PERMEABILITY: Well drained. Runoff is medium. Permeability is moderate.
USE AND VEGETATION: Most areas are in crops or pasture. Original vegetation was presumably mixed hardwoods.
DISTRIBUTION AND EXTENT: West Virginia, Pennsylvania, Maryland, Virginia, Ohio, Kentucky, Indiana, Illinois, Michigan, Missouri, and Tennessee. Total Extent is large.
MLRA OFFICE RESPONSIBLE: Morgantown, West Virginia
