TYPE LOCATION: Washington County, Maryland; 5.2 miles north of ATT tower access road and its over pass of Lanes Run. East of Lanes Run 400 feet, in the Forsythe area. Lat. 39 degrees 42' 29" and Long. 77 degrees 57' 37"
RANGE IN CHARACTERISTICS: Solum thickness ranges from 40 to 60 inches. Depth to lithologic discontinuity is 30 to 60 inches. Lithic contact greater than 60 inches. Content of rock fragments ranges from 10 to 45 percent in the solum and 15 to 60 percent in the substratum. Rock fragments consist of sandstone gravels, cobbles, and stones in the upper solum. Channers and flags from acid and calcareous shales are dominant in the lower solum and substratum. Rock fragments are less than 35 percent in the particle size control section. The soil ranges from slightly acid too extremely acid throughout.

The Ap horizon, where present, has hue of 1OYR, value of 3 through 5, chroma 2 through 4. Texture silt loam or loam, in the fine earth fraction. Reaction ranges from moderately acid to slightly acid. (where limed)
The E horizon, where present, has hue of 1OYR, value of 4 through 6, chroma 4 through 8. Texture is silt loam or loam in the fine earth fraction.
The BE horizon, where present, has hue of 1OYR of 7.5YR, value 4 through 6, chroma 4 through 8. Texture is silt loam or loam in the fine earth fraction.
The Bt horizon has hue of 5YR through 7.5YR, value 4 through 6, chroma 4 through 6. it is silt loam, loam, clay loam, and silty clay loam in the fine earth fraction.
The 2Bt horizon has hue of 2.5YR through 7.5YR, value 4 through 6, chroma 4 through 8. Texture is clay loam, silty clay loam, or clay in the fine earth fraction. Depth to discontinuity ranges form 30 to 45 inches.
The 2BC horizon, where present, has hue of 5YR through 1OYR, value 4 through 6, chroma 4 through 8. Texture is loam, silt loam, silty clay loam, or clay loam in the fine earth fraction.
COMPETING SERIES: Brumbaugh soils in the only known soil in the same family. Soils in similar or closely related families are the Birdsboro, Chilmark, Hassler, Roselle, Thurmont, and Tulip series. The Brumbaugh and Thurmont soils formed in colluvium from metamorphic rocks and have a lithologic discontinuity from 30 to 60 inches. Chilmark soils formed in a loamy or sandy aeolian mantle over coastal plain sediments on the islands of Nantucket and Martha's Vineyard in MLRA 149B. Hassler soils are deep to granite bedrock and formed in colluvium and residuum on mountain ridges in the Ozark Highland area (MLRA 116A). Roselle soils formed in colluvium and residuum from granite on terraces and footslopes in mountain basins in the Ozark Highland area (MLRA 116A). Tulip soils formed in colluvium from sandstone and siltstone and in residuum from underlying shale in south central Indiana (MLRA 120). The Birdsboro soils formed in old alluvial deposits from shale, sandstone, or siltstone.
GEOGRAPHIC SETTING: Sideling soils are on footslopes and colluvial fans below ridges capped by sandstone. They form in acid sandstone colluvium over shale residuum. Slopes range from 3 to 45 percent. Mean annual precipitation ranges from 40 to 46inches. Mean annual temperature ranges from 48 to 56 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: Berks, Buchannan, Calvin, Dekalb, Hazelton, and Weikert soils are on adjacent landscapes. The Berks, Calvin, Dekalb, and Weikert soils are moderately deep or shallow to bedrock and are formed in residuum. Buchanna soils have a Fragipan. Hazelton soils are well drained.
DRAINAGE AND PERMEABILITY: Moderately well drained. Permeability is moderately slow in the upper solum and slow in the lower solum and substratum. Run off is slow on gentle slopes and high on steeper slopes.
USE AND VEGETATION: Most of these soils are in Oak Hickory forest. Areas that are gently or strongly sloping may be pastured or in orchard.
DISTRIBUTION AND EXTENT: Maryland, Pennsylvania, Virginia, and West Virginia. The soils of this series are not extensive. (MLRA147)
