TYPE LOCATION: Vernon Parish, Louisiana; 600 feet west of stream, 100 feet south of gravel road on West Louisiana Experiment Station, sec. 27, T. 1 S., R. 9 W.
RANGE IN CHARACTERISTICS: The solum thickness ranges from 60 to 90 inches. Reaction ranges from very strongly acid to slightly acid in the A and E horizons and from extremely acid to moderately acid in the Bt and Btg horizons. Ironstone or quartz gravel range from none to common throughout the solum.
The A or Ap horizon has hue of 10YR or 2.5Y, value of 3 to 6, and chroma of 1 to 4. Texture is very fine sandy loam, loam, silt loam, fine sandy loam, or sandy loam.
The E horizon has hue of 10YR or 2.5Y, value of 4 to 6, and chroma of 2 to 5. It is sandy loam, fine sandy loam, very fine sandy loam, loam, or silt loam.
A BA or BE horizon is in some pedons. Where present, it has hue of 7.5YR, 10YR, or 2.5Y, value of 4 to 7, and chroma of 3 to 6. Texture is sandy loam, fine sandy loam, very fine sandy loam, or sandy clay loam.
The Bt horizon has hue of 10YR or 7.5YR, value of 4 to 6, and chroma of 4 to 8. The lower part of the Bt horizon has hue of 2.5Y in some pedons. Grayish iron depletions range from few to common within a depth of 30 inches below the soil surface. Reddish or yellowish iron accumulations range from common to many in the lower part of the Bt horizon. Texture of the Bt horizon is silty clay loam, clay loam, silty clay, or clay. Clay content ranges from 35 to 60 percent.
The Btg, BCg, and Cg horizons are gray with iron accumulations in shades of brown or red or they are variegated with these colors. Texture is silty clay loam, clay loam, silty clay, or clay.
COMPETING SERIES: These include the Chrylser, Subran and Tiak series in the same family. Chrysler soils have a lower shrink-swell potentials and typically have hues redder than 7.5YR in the subsoil. Subran soils have significant accumulations of black nodules and stains in the argillic horizon and do not contain Btg horizons in the lower part of the solum. Tiak soils have redder hues in the upper part of the Bt horizon.
GEOGRAPHIC SETTING: Angie soils are on broad level to strongly sloping Coastal Plains. The regolith is marine or stream deposited loamy and clayey sediment. The climate is warm and humid. Mean annual temperature ranges from 57 to 68 degrees F. and average rainfall averages 45 to 59 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These include Kirvin, Sacul, Sawyer, Shubuta, Susquehanna, Vaiden and Wilcox series. Kirvin and Sacul soils have Bt horizons with more than 20 percent decrease in clay content in the upper 60 inches of the solum. Sawyer soils contain less than 35 percent clay on the upper part of the argillic horizon. Shubuta soils do not have aquic conditions within 30 inches of the soil surface. Susquehanna soils are somewhat poorly drained and higher shrink-swell potential. Vadian and Wilcox soils have smectitic mineralogy and intersecting slickensides within 40 inches of the soil surface.
DRAINAGE AND PERMEABILITY: Angie soils are moderately well drained. Runoff is medium to rapid. Permeability is slow. A water table is at a depth of 2 to 5 feet during winter and early spring.
USE AND VEGETATION: Almost all areas of Angie soils are in forest of mixed hardwood and pine. A small amount is used for pasture.
DISTRIBUTION AND EXTENT: Coastal Plain of Alabama, Arkansas, Georgia, Louisiana, Mississippi, South Carolina, Virginia, and possibly Oklahoma and Texas. The area of the Angie soil is of large extent.
MLRA OFFICE RESPONSIBLE: Little Rock, Arkansas

REMARKS: Diagnostic horizons recognized in this pedon are:
Ochric epipedon - the zone from the surface of the soil to a depth of about 10 inches (Ap and E horizons)
Argillic horizon - the zone from about 10 to 65 inches (Bt1, Bt2, Bt3, Btg, and BCg horizons)
