TYPE LOCATION: Elliott County Kentucky; on a high stream terrace. Along KY Route 649, about 1660 feet southwest of Ibex and about 130 feet west of KY Route 649 in a wooded area owned by the U.S. Department of the Army Corps of Engineers. Latitude 38 degrees 10 minutes 21.50 seconds north and longitude 83 degrees 4 minutes 31.20 seconds west, NAD83
RANGE IN CHARACTERISTICS: Solum thickness ranges from 40 to 80 inches. Depth to the fragipan ranges from 18 to 29 inches. Volume of rock fragments ranges from 0 to 15 percent above the fragipan, from 0 to 15 percent in the fragipan, and from 0 to 35 percent in the C horizon. The soil ranges from very strongly acid to Neutral. Depth to bedrock ranges from 60 to 80 inches. A lithologic discontinuity may or may not be present in this series. This series is frequently ponded during the winter months from 0 to 7 centimeters (0 to 3 inches) deep.
RANGE OF INDIVIDUAL HORIZONS:
The Ap horizon has hue of 10YR or 2.5Y, values of 4 or 5, and chroma of 2 to 4. In undisturbed areas, an A horizon less than 7 inches thick is present and ranges from dark brown (10YR 3/3) to dark yellowish brown (10YR 4/4). Texture of the A and Ap horizons is silt loam, loam, or fine sandy loam in the fine-earth material.
The E horizon (where present) has hue of 10YR or 2.5Y, values of 4 or 5, and chroma of 2 to 4. Texture of the E horizon is silt loam, loam, or fine sandy loam in the fine-earth material.
The Bt horizon has hue of 10YR or 2.5Y, value of 4 to 7, and chroma of 4 to 8. Texture of the fine-earth material is silt loam, loam, fine sandy loam or sandy clay loam.
The Btx horizon has hue of 7.5YR to 2.5Y, values of 4 to 7, and chroma of 1 through 8. The expression of the fragipan is strong. Texture of the fine-earth material is silt loam, loam, sandy clay loam, clay loam or fine sandy loam.
The C horizon has hue of 7.5YR to 2.5Y, value of 4 to 7, and chroma of 1 to 8. Texture of the fine-earth material is sandy loam, loam, silt loam, silty clay loam, fine sandy loam or clay loam.
COMPETING SERIES: There are no competing series in this family.
GEOGRAPHIC SETTING: Caneycreek soils are found on high stream terraces along major rivers and steams, commonly separated from a constructional valley floor by steep hillslopes. Caneycreek soils formed in old alluvium derived largely from acid sandstone siltstone and shale. Thickness of the alluvium ranges from 60 inches to 80 inches or more. Slope ranges from 0 to 20 percent. Mean annual precipitation is about 1088 mm (43 inches), and mean annual air temperature is about 11.5 degrees C. (53 degrees F).
GEOGRAPHICALLY ASSOCIATED SOILS: These include Allegheny, Cotaco, Ezel, Gilpin, Guyan, Monongahela, Purdy, Riney, Tilsit and Tygart. Allegheny soils do not have a fragipan and are well drained and fine-loamy. Cotaco soils do not have a fragipan and fine-loamy. Ezel soils do not have a fragipan and are well drained, deep and fine-loamy. Gilpin soils do not have a fragipan are well drained, moderately deep and fine-loamy and are located on areas where the alluvial deposits have been lost to erosion. Guyan soils do not have a fragipan and are fine-loamy. Monongahela soils are moderately well drained and fine-loamy. Purdy soils do not have a fragipan and are fine and poorly drained. Riney soils do not have a fragipan and are well drained and fine-loamy. Tilsit soils are moderately well drained and fine-silty. Tygart soils do not have a fragipan and are fine.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained. The potential for surface runoff potential is high. KSAT is moderately low.
USE AND VEGETATION: Most areas, but not all, have been cleared of the original hardwood forest and used for pasture, cultivated crops, and industrial or residential sites.
DISTRIBUTION AND EXTENT: This series is mapped only in Kentucky at present. The series is of small extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Morgantown, West Virginia
SERIES ESTABLISHED: Elliott County, Kentucky, 2007.
REMARKS: Caneycreek soils were previously mapped as Tyler in the 1965 soil survey of Elliott County. These areas were found to be coarse-loamy, not fine-silty. The series was proposed in Elliott County, Kentucky, 2005.
This series has a deep analogue that may be developed into a new series if enough acres are identified in other parts of the MLRA.
The 01/2008 revision changes the status from tentative to established. Additionally, other minor edits were completed.
