(USGS Lloyd Shoals Dam topographic quadrangle (1964), Latitude 33 degrees 18 minutes 44 seconds N., Longitude 83 degrees 50 minutes 20 seconds W.)
RANGE IN CHARACTERISTICS:
Depth to the Base of the Argillic: 20 to 40 inches
Depth to Bedrock: 20 to 40 to soft bedrock and greater than 40 to hard bedrock
Depth to Seasonal High Water Table: Greater than 72 inches
Content and size of rock fragments: 15 to 70 percent, by volume, in the A and 35 to 70 percent in the B and C horizons; mostly gravel, channers, cobbles, and stones from sillimanite schist, mica schist, or quartz mica gneiss
Soil Reaction: Very strongly to strongly acid, except where limed
Other Features: Most pedons have few to common flakes of mica
RANGE OF INDIVIDUAL HORIZONS:
A horizon:
Color--hue of 5YR to 10YR, value of 3 to 5, and chroma of 2 to 6. A horizons with moist value of 3 or less are less than 7 inches thick.
Texture (fine-earth fraction)--sandy loam
E horizon (if it occurs):
Color--hue of 7.5YR or 10YR, value of 4 to 6, and chroma of 4 to 6
Texture (fine-earth fraction)--sandy loam
BA horizon or BE horizon (if it occurs):
Color--hue of 5YR to 10YR, value of 4 to 6, and chroma of 4 to 6
Texture (fine-earth fraction)--sandy loam or loam
Bt horizon:
Color--hue of 5YR to 10YR, value of 4 to 6, and chroma of 4 to 8
Texture (fine-earth fraction)--sandy clay loam, clay loam, or loam
C horizon (if it occurs):
Color--hue of 5YR to 10YR, value of 4 to 6, and chroma of 4 to 8
Texture (fine-earth fraction)--sandy clay loam, clay loam, or loam
Cr horizon:
Type of bedrock--multicolored, weathered sillimanite schist with occasional interbeds of mica schist and quartz mica gneiss. Soil material often extends downward into nearly vertical cracks in this horizon.
R horizon:
Type of bedrock--unweathered fractured sillimanite schist, mica schist, or quartz mica gneiss
COMPETING SERIES: Cliffside and Lockhart soils are in a similar family. Cliffside soils have a lithic contact above 40 inches. Lockhart soils formed in material mostly weathered from porphyritic granite, have sola 40 to 60 inches thick and are very deep to a lithic contact.
