County: Hancock
State: Tennessee
USGS Quadrangle: Sneedville, TN
Latitude (Decimal Degrees, NAD83): 36.5097222
Longitude (Decimal Degrees, NAD83): -83.1544444
Directions to the pedon: Follow Highway 66 about 2.5 mile south from where it turns south from the Clinch River, turn left on gravel road at Stony Gap Baptist church, then right on the next gravel road. Following the gravel roads about 1 km (0.5 mile) from the church, the site is about 13 meters (40 feet) north of the second gravel road.

Range of Individual Horizons:
A or Ap horizon:
Color: hue of 10YR, value of 4 or 5, and chroma of 2 or 3
Texture (fine earth fraction): silt loam, loam, or rarely sandy loam. A few areas have a layer of recent overwash that is yellowish red or strong brown silty clay loam.
Bw horizon:

Ab horizon (when present):
Color: hue of 10YR, value of 3, chroma of 2 or 3
Texture (fine earth fraction): silt loam or loam
Bwb horizon (when present):
Color: hue of 10YR or 7.5YR, value of 4 or 5, and chroma of 4 to 6
Texture (fine earth fraction): silt loam, loam, silty clay loam, or clay loam
Other: clay films are sometimes present in this horizon. Redoximorphic depletions in shades of gray occur in places.
