LOCATION OGLES VAEstablished Series
TAXONOMIC CLASS: Loamy-skeletal, siliceous, active, mesic Fluventic Dystrudepts
TYPICAL PEDON: Ogles on a 1 percent forested slope, along a creek bank. (Colors are for moist soil unless otherwise stated)
A-- 0 to 5 inches; very dark grayish brown (10YR 3/2) very cobbly loam; weak fine granular structure; very friable, nonsticky, nonplastic; many very fine, fine and medium roots, and few coarse roots; 35 percent sandstone cobbles and 23 percent sandstone pebbles; strongly acid; clear smooth boundary. (2 to 10 inches thick)
Bw-- 5 to 28 inches; yellowish brown (10YR 5/4) extremely cobbly sandy loam; weak fine granular structure; very friable, nonsticky, nonplastic; many very fine, fine and medium roots; 37 percent sandstone cobbles and 30 percent sandstone pebbles; strongly acid; gradual smooth boundary. (10 to 36 inches thick)
C1-- 28 to 47 inches; yellowish brown (10YR 5/4) extremely gravelly sandy loam; weak coarse granular structure; very friable, nonsticky, nonplastic; common very fine and fine roots; 41 percent sandstone pebbles and 30 percent sandstone cobbles; strongly acid; gradual smooth boundary.
C2-- 47 to 60 inches; yellowish brown (10YR 5/4) very cobbly sandy loam; weak coarse granular structure; very friable, slightly sticky, nonplastic; few very fine and fine roots; 30 percent sandstone cobbles and 25 percent sandstone pebbles; strongly acid.
TYPE LOCATION: Alleghany County, Virginia in a forested area along the bank of Ogles Creek. U.S.G.S. Callaghan topographic quadrangle; Latitude 37 degrees 49 minutes 34 seconds N and Longitude 80 degrees 07 minutes 01.7 seconds W; NAD 1927.
RANGE IN CHARACTERISTICS: Solum thickness ranges from 20 to 40 inches. Depth to bedrock is more than 60 inches. Average content of gravel, cobble and stone size rock fragments range from 15 to 60 percent in the A horizon, and from 35 to 85 percent in the B and C horizons. Thin layers or lenses with less rock fragments may occur. Reaction is very strongly acid to moderately acid throughout.
The A horizon has hue of 7.5YR or 10YR, value of 2 to 4, and chroma of 2 to 4. It is loam, sandy loam or fine sandy loam. A horizons with value of 3 are less than 7 inches thick.
Some pedons have a BA horizon with hue of 7.5YR or 10YR, value of 2 to 5, and chroma of 2 to 6. It is loam, sandy loam or fine sandy loam.
The Bw horizon has hue of 7.5YR or 10YR, value of 4 or 5, and chroma of 4 to 6. It is loam or sandy loam.
The C horizon has hue of 7.5YR or 10YR, value of 4 or 5, and chroma of 3 to 6. It is sandy loam or loamy sand.
COMPETING SERIES: There are no other series in this family. The Craigsville soils are closely related, but are in a mixed mineralogy family.
GEOGRAPHIC SETTING: Ogles soils formed in loamy-skeletal sediments from sandstones and shales and are on flood plains. Slope gradients range from 0 to 5 percent. Climate is humid continental. Mean annual air temperature ranges from 50 to 54 degrees F., mean annual precipitation ranges from 35 to 50 inches, and elevation ranges from 1100 to 2200 feet above sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Alonzville, Coursey, Gladehill, Irongate, and Wolfgap soils. Alonzville and Coursey soils are on low stream terraces and have a fine loamy argillic horizon. Gladehill, Irongate and Wolfgap soils have a mollic epipedon. In addition, Irongate soils are moderately well drained.
DRAINAGE AND PERMEABILITY: Ogles soils are well drained. The potential for surface runoff potential is negligible. Permeability is moderately rapid. These soils are subject to flooding.
USE AND VEGETATION: Most areas remain in their natural vegetation. Some areas have been cleared and are used as pasture. The overstory in most forested areas consists of sycamore, red maple, black locust, white oak, Virginia pine, and yellow-poplar. The understory consists of flowering dogwood, eastern white pine, cedar, blackberry, poison ivy, Virginia creeper and greenbrier.
DISTRIBUTION AND EXTENT: MLRA 128, Appalachian Ridge and Valley areas in Virginia. The soils are of small extent.
