TYPE LOCATION: Beaufort County, South Carolina; 3.5 miles
northeast of Gardens Corner; 165 feet southeast of U.S. Highway
17. Elevation is about 12 feet.
RANGE IN CHARACTERISTICS: Solum thickness is 50 to more than 72 inches. The soil is very strongly acid to slightly acid in the A horizon and extremely acid to strongly acid throughout the rest of the profile. Few to common fine flakes of mica are in the B and C horizons of some pedons.
The A or Ap horizon has hue of 7.5YR to 2.5Y, or it is neutral,
value of 3 to 6, and chroma of 0 to 3. Where the value is less
than 3.5, the horizon is less than 6 inches thick.
The E horizon, where present, has hue of 10YR or 2.5Y, value of 5
to 7, and chroma of 2 to 4. The A and E horizon is fine sandy
loam, sandy loam, loamy fine sand, or loamy sand.
The Bt horizon has hue of 10R to 5YR, value of 4 or 5, and chroma
of 6 or 8, commonly with mottles in shades of red, brown, or
yellow. Some pedons are mottled in shades of red, brown, and
yellow. The Btg horizon has hue of 10YR to 5Y, value of 5 to 8,
and chroma of 1 or 2, commonly with mottles in shades of red,
brown, yellow, gray, or it is mottled in shades of gray, red,
brown, or yellow. The Bt and Btg horizon is clay or sandy clay.
The particle size control section averages 45 to 65 percent clay.
The BCg horizon has the same colors as the Btg horizon. It is
sandy clay, sandy clay loam, or sandy loam.
The C horizon has hue of 10YR to 5Y, value of 5 to 8, and chroma
of 1 to 3. It is sandy clay loam, fine sandy loam, sandy loam, or loamy sand.

Wahee series in similar families. Annemaine soils have a Bt horizon with Ca and Mg content averaging about 3 meg/100 gms. Beason and Eulonia soils have less than 45 percent clay in the particle size control section. Craven,
Creedmoor, Dogue, Helena, Newco, Peawick, and Wolftever soils do not have colors in shades of red in the upper part of the argillic horizon. Lignum, Rosenwall, and Vinita soils have a solum less than 40 inches thick. Sacul soils are underlain by shale and have a seasonal high water table at a depth greater than 6 feet. Peawick soils have aluminum saturation greater than 50 percent. Stapp soils have 15 to 30 percent fragments of shale in the B3 horizon. Angie, Caroline, Dunbar, Duplin, Lenoir, Persanti,
Pooler, Shubuta, and Tiak soils have less than 20 percent clay decrease from the maximum within 60 inches of the surface. Wahee soils have gray mottles throughout the argillic horizon.
GEOGRAPHIC SETTING: These soils are on the Pamlico and Talbot terraces of the lower Coastal Plain. Slopes range from 0 to 6 percent but are dominantly less than 2 percent. The soil formed in clayey marine sediments; dominantly of fine texture. Near the type location the mean annual temperature is 66 degrees F., mean annual precipitation is 45 inches, and frost-free season is about
257 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the similar and
competing
Caroline,
Craven,
Eulonia,
Pooler,
Lenoir, and Wahee
series plus the
Argent,
Bladen,
Bertie,
Coosaw, and
Yemassee
series. Bertie, Coosaw, and Yemassee soils have 18 to 35 percent clay in the particle size control section. Argent and Bladen
soils are poorly drained and are dominantly gray throughout.
DRAINAGE AND PERMEABILITY: Moderately well drained; moderate
surface runoff; slow permeability. A water table is within 1.5 to 2.5 feet of the surface for as much as 4 months during most years.
USE AND VEGETATION: About half of the area is in woodland and the remainder is in pasture or cropped to corn, soybeans, or small
grain. Woodland consists of loblolly pine, longleaf pine, and
slash pine, oaks, hickory, and sweetgum.
DISTRIBUTION AND EXTENT: Coastal Plain of South Carolina and possibly Georgia, North Carolina, and Virginia. The series is of moderate extent.
