TYPE LOCATION: Stone County, Arkansas; about 3 miles southeast of Mountain View on Highway 5; in SE1/4SE1/4NE1/4 sec. 20, T. 14 N., R. 10 W.
RANGE IN CHARACTERISTICS: Solum thickness and depth to hard bedrock ranges from 40 to 60 inches. Reaction ranges from very strongly acid to neutral in the A and E horizons and from strongly acid to mildly alkaline in the BA, B and C horizons.
The A horizon has hue of 10YR, value of 3, 4, or 5, and chroma of 2 or 3. Horizons with mollic colors are less than 7 inches in thickness. Texture of the A horizon is silt loam, silty clay loam, loam, or with stony or flaggy modifiers.
The E horizon, where present, has hue of 10YR, value of 4 or 5, and chroma of 2, 3, or 4. Texture of the A horizon is silt loam, silty clay loam, loam, or with stony or flaggy modifiers.
The BA horizon has hue of 7.5YR or 10YR, value of 4 or 5, and chroma of 4 or 6. Texture is silty clay, clay loam, silty clay loam, or with flaggy modifiers.
The Bt horizon has hue of 10YR or 7.5YR, value of 4 and chroma of 4, or value of 5 and chroma of 4 to 6. Iron accumulations and depletions are in shades of brown or red. Texture is silty clay loam, silty clay, or clay. Flaggy phases are recognized.
The BC and C horizon, where present, have hue of 10YR, 7.5YR, or 2.5Y, value of 5 or 6, and chroma of 4 or 6. Iron accumulations and depletions are in shades of brown, red, or gray. Texture is the same as for the Bt horizon. Some C horizons are equally variegated in shades of brown and gray. Calcium carbonate concretions are none to few.
The Cr horizon is partly weathered interbedded limestone, alkaline shale, and siltstone. Vertical fractures and some pedons do not have a Cr horizon. Seams of 0.25 to 0.5 inches in width are commonly silty clay or clay.
The underlying R horizon is hard, gray limestone bedrock
COMPETING SERIES: These are the Beasley, Bland, Bonnell, Brashear, Bratton, Briggsville, Brookside, Caneyville, Cantwell, Chrome, Derinda, Donahue, Eden, Edenton, Elba, Eldean, Estate, Faywood, Fredonia, Hagerstown, Heitt, Kewaunee, Lamoille, Lewisburg, Lowell, Markland, Medary, Miamian, Milton, Ozaukee, Shrouts, Upshur, Vandalia, Vincent, Woodsfield, and Wynn series. Bland, Bratton, Caneyville, Cantwell, Chrome, Derinda, Donahue, Eden, Edenton, Faywood, Fredonia, Milton, Shrouts, and Wynn soils have lithic or paralithic contacts within 40 inches. Beasley, Briggsville, Eldean, Heitt, Kewaunee, Lewisburg, Markland, Medary, Miamian, and Ozaukee soils have solums of less than 40 inches in thickness. Bonnell, Brashear, Brookside, Lowell, and Woodsfield soils have silt loam and silty clay loam A horizons with less than 5 percent coarse fragments in the upper part of the solum. Elba soils have carbonates within depths of 30 inches. Bonnell soils formed in thin loess and till; Vincent soils formed in lacustrine material. Hagerstown, Upshur, and Vandalia soils have hue of 5YR or redder hue throughout the B horizon. Upshur soils have solums ranging from 26 to 50 inches. Estate soils have redder B horizons and formed in residuum weathered from interbedded sandstone and limestone. Lamoille soils have loamy-skeletal IIB horizons above 40 inches.
GEOGRAPHIC SETTING: Newnata soils are on gently sloping ridgetops to very steep side slopes of the Ozark Highlands. Slopes range from 3 to 60 percent. These soils formed in residuum weathered from interbedded limestone, alkaline shale, and siltstone. Near the type location, average annual temperature ranges from 54 degrees to 57 degrees F., and average annual precipitation ranges from 46 to 49 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Eden, Moko, and Summit series. Eden soils are moderately deep to bedrock and are on higher elevations of the uplands. Moko soils have sola 6 to 20 inches thick, loamy-skeletal control sections and are on steeper adjacent side slopes. Summit soils are more than 60 inches to bedrock, have darker surface layers and grayer subsoils and are on foot slopes.
DRAINAGE AND PERMEABILITY: Newnata 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, northern red oak, shortleaf pine, black locust, hackbery, green ash, black gum, shagbark hickory, and white oak. Tame grasses are mainly bermudagrass and tall fescue. Native vegetation is mixed hardwoods and pine.
DISTRIBUTION AND EXTENT: Ozark highlands of Arkansas. Possibly in Missouri. The series is of moderate extent.
