RANGE IN CHARACTERISTICS:
Thickness of sandy horizons: 80 inches or more. The 10 to 40 inch control section contains 10 to 25 percent fines
Depth to Bedrock: Greater than 80 inches
Depth to Seasonal High Water Table: 18 to 36 inches, December to April
Soil Reaction: extremely acid to strongly acid except where the surface has been limed
A or Ap horizon:
Color--hue of 10YR or 2.5Y, value of 3 through 6, and chroma of 1 to 4
Texture--loamy sand, loamy fine sand, sand, or fine sand
C horizon (upper part):
Colorhue of 10YR or 2.5Y, value of 5 to 7, and chroma of 3 through 8
Texture--sand, loamy sand, fine sand, coarse sand, or loamy fine sand
C horizon (lower part):
Color10YR or 2.5Y, value of 5 to 8, and chroma of 3 or 4
Texture--sand, loamy sand, fine sand, coarse sand, or loamy fine sand
Redoximorphic features--iron depletions with chroma of 2 or less may occur in some pedons within a depth of 20 inches. Iron masses in shades of yellow, brown, or red are found in some pedons.
The upper part of the C horizon has hue of 10YR or 2.5Y, value of 5 to 7, and chroma of 3 through 8. The lower part of the C horizon has hue of 10YR or 2.5Y, value of 5 to 8, and chroma of 3 or 4. Iron depletions in shades of gray are at depths of less than 40 inches, and may occur within a depth of 20 inches. The lower C horizon in some pedons is mottled with redoximorphic features in shades of gray, yellow, brown, or red. Clean sand grains are in the lower part of the C horizon in most pedons. Texture is sand, loamy sand, fine sand, coarse sand, or loamy fine sand.
The Cg horizon, where present, has hue of 10YR or 2.5Y, value of 5 to 7, and chroma of 1 or 2. Soft masses of iron accumulation in shades of red, yellow, or brown range from none to many. Texture is the same as for the C horizon.

MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Raleigh, North Carolina
SERIES ESTABLISHED: Pitt County, North Carolina; 1969.
REMARKS: This series was previously included in the Klej series, but Klej is in a mesic family. Diagnostic horizons and features recognized in the typical pedon are:
Ochric epipedon - the zone from the surface to a depth of 8 inches (Ap horizon)
Aquic conditions - redoximorphic features beginning in the zone between 25 and 40 inches (C3 horizon), and also present in the Cg horizon at 40 to 80 inches.
