RANGE IN CHARACTERISTICS: Solum thickness ranges from 40 to 60 inches. Depth to hard bedrock ranges from 40 to 72 inches. Some pedons have a thin Cr horizon. The reaction ranges from strongly acid to neutral in the A and E horizons and medium acid to neutral in the B horizons.
The A horiozn has hue of 10YR, value of 4, and chromas of 2, 3, or 4. Textures are stony sandy loam, stony fine sandy loam. Gravelly and cobbly phases are recognized, with total coarse fragments by volume ranging from 15 to 30 percent.
The E horizon has hue of 10YR, value of 4 or 5, and chromas of 2, 3, or 4. Textures are stony sandy loam, stony fine sandy loam. Gravelly and cobbly phases are recognized, with total coarse fragments by volume ranging from 15 to 30 percent.
The BA horizon has hue of 7.5YR, or 5YR, value of 3 or 4, and chroma of 6 or 8. Texture is sandy loam, clay loam, sandy clay loam, gravelly clay loam, or gravelly sandy clay loam. The coarse fragments, dominantly gravel size, range from 5 to 25 percent by volume.
The Bt horizon has hue of 2.5YR or 5YR, value of 4 or 5, and chroma of 5 or 8. Texture is clay, sandy clay, clay loam, gravelly clay loam, or cobbly clay loam. Iron accumulations and depletions are in shades of brown and red. The coarse fragments, dominantly gravel size, ranges from 0 to 25 percent by volume.
The Cr horizon, if present, is weathered limestone and sandstone with shades of red, brown, and yellow.
The R layer is hard undulating limestone and sandstone with few cracks that have horizontal spacing of 6 inches or more.
COMPETING SERIES: These are the Bardley, Beasley, Bland, Brashear, Bratton, Briggsville, Brookside, Caneyville, Carbo, Chrome, Derinda, Donahue, Eden, Edenton, Elba, Eldean, Faywood, Fredonia, Gatewood, Hagerstown, Heitt, Kewaunee, Lewisburg, Lowell, Markland, Medary, Miamian, Milton, Ozaukee, Shrouts, Solway, Switzerland, Upshur, Vandalia, Vincent, Woodsfield, and Wynn series. Bardley, Bland, Bratton, Caneyville, Carbo, Chrome, Derinda, Donahue, Eden, Edenton, Faywood, Fredonia, Gatewood, Lewisburg, Milton, Solway, Shrouts, and Wynn soils have lithic or paralithic contacts within 40 inches. Beasley, Briggsville, Eldean, Heitt, Kewaunee, Lewisburg, Markland, Medary, Miamian, Ozaukee, and Upshur soils have solums of less than 40 inches. Brashear, Brookside, Hagerstown, Lowell, and Woodsfield soils have silt loam, and silty clay loam A horizons with less than 15 percent limestone fragments. Elba soils have carbonates within depths of 30 inches. Vandalia soils do not have bedrock within depths of 72 inches. Vincent soils formed in lacustrine material. In addition, Beasley, Brashear, Brookside, Faywood, Heitt, Lowell, and Shrouts soils have 7.5YR or yellower hues in the B horizons.
GEOGRAPHIC SETTING: Estate soils are on gently sloping to steep sideslopes of the Ozark Highlands. Slopes range from 3 to 40 percent. These soils formed in residuum weathered from interbedded limestone and sandstone. Mean annual precipitation near the type location is about 45 inches and the mean annual air temperature is about 57 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Britwater, Brockwell, Moko and Portia series. Britwater soils have fine-loamy control sections and are on terrace positions. Brockwell soils have coarse-loamy control sections and are on higher elevations of the uplands. Moko soils have sola 6 to 20 inches thick, loamy-skeletal control section and are on steeper adjacent sideslopes. Portia soils have fine-loamy control section and are on nearby upland sideslopes
DRAINAGE AND PERMEABILITY: Estate soils are well drained and have slow permeability. Runoff is medium to rapid.
USE AND VEGETATION: Principal use is woodland with some areas used for pasture. Forest vegetation includes eastern redcedar, southern red oak, shortleaf pine, black walnut, white oak, and black cherry. Tame grasses are mainly bermuda and tall fescue.
DISTRIBUTION AND EXTENT: Ozark Highlands of Arkansas. Possibly in Kentucky, Tennessee, and Missouri. The series is of moderate extent.
