TYPE LOCATION: Rhea County, Tennessee. From Dayton, 1.8 miles northwest on State Route 30, 0.5 miles southwest on State Route 303 (Cove Road), 200 feet north of State Route 303 about 100 feet north of Sale Creek; USGS Morgan Springs topographic quadrangle; Latitude 35 degrees, 30 minutes, 15 seconds N. and Longitude 85 degrees, 02 minutes, 52 seconds W., NAD 1927.
RANGE IN CHARACTERISTICS: Solum thickness ranges from 14 to 40 inches. Depth to bedrock is greater than 60 inches. Rock fragments are mostly subrounded and rounded sandstone and chert graveland range from 0 to 5 percent in the A horizon, from 0 to 30 percent in the B horizon, and from 0 to 40 percent below the solum. Reaction ranges from moderately acid to moderately alkaline. Some profiles may have a buried argillic horizon below 40 inches.
The Ap horizon has hue of 10YR or 2.5Y, value of 4 or 5 and chroma of 2 to 4. Texture is loam, silt loam, or silty clay loam.
The Bg horizon has hue of 10YR to 5Y or neutral, value of 4 to 6, and chroma of 0 to 2. Mottles and redoximorphic features are in shades of yellow, brown, red, or gray and range from few to many. Texture is silty clay loam, sandy clay loam, clay loam, loam, or sandy loam.
The Cg horizon has hue of 10YR to 5Y, or neutral, value of 4 to 7, and chroma of 0 to 2. Mottles and redoximorphic features are in shades of yellow, brown, red, or gray and range from few to many. Texture is sandy loam, silty clay loam, sandy clay loam, clay loam, or loam. Below 50 inches texture may include their gravelly analogues.
COMPETING SERIES: There are no other series in this family. Soils in similar families include Atkins, Holderton, and Wehadkee series. Atkins soils are in a fine-loamy, acid family, are the mesic temperature regime, and formed in alluvium washed from acid shale and sandstone. Holderton soils are in a mesic temperature regime and formed in alluvium from glacial drift. Wehadkee soils are in a fine loamy family and formed in alluvium from the Blue Ridge and Southern Peidmont MLRA's.
GEOGRAPHIC SETTING: Cranmore soils are on nearly level flood plains, and in depressions. They also occur occasionally in small drainageways. Slopes are 0 to 2 percent. The typical pedon is located in a valley that receives alluvium from both the Cumberland Plateau and Mountains and the Southern Appalachian Ridges and Valleys MLRA's. These soils formed in mixed alluvium from sandstone, shales, siltstone and limestone. The mean annual air temperature is 59 degrees F., and mean annual precipitation is 55 inches near the type location.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Allen, Shady, Hamblen and Pettyjon soils. Allen soils, on adjacent uplands and footslopes, are deep, well drained, and have an argillic horizon. Shady soils, on adjacent terraces, are well drained and have an argillic horizon. Hamblen soils, on flood plains at slightly higher elevations, are moderately well drained. Pettyjon soils, on flood plains at slightly higher elevations, are well drained.
DRAINAGE AND PERMEABILITY: Very poorly or poorly drained; very slow runoff; moderate or moderately rapid permeability.
USE AND VEGETATION: Most areas of this soil are cleared. It is used for hay and pasture. Wooded areas consist of American sycamore, water oaks, sweetgum and willows.
DISTRIBUTION AND EXTENT: The Southern Appalachian Ridges and Valleys (MLRA 128)of Tennessee. The series is of small extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Morgantown, West Virginia
SERIES ESTABLISHED: Rhea County, Tennessee; 2000.
REMARKS: These soils were formerly included in the Atkins series. This soil will be used in the thermic part of the Southern Appalachian Ridges and Valleys.
Diagnostic horizons recognized in this pedon are:
Ochric epipedon - 0 to 5 inches (Ap horizon),
Cambic horizon - 5 to 24 inches (Bg horizon),
Redoximorphic features: iron depletions and accumulations in each horizon below the A horizon, created by oxidation and/or reduction of iron during saturation of the soil with water.
