(6 to 12 inches thick)
BC--17 to 22 inches; olive gray (5Y 4/2) extremely channery silt loam; weak thin platy structure; friable; thin discontinuous clay films on faces of peds and lining pores; 70 percent rock fragments; neutral; clear wavy boundary. (5 to 14 inches thick)
Cr--22 to 51 inches; grayish brown (2.5Y 5/2) saprolite that can be crushed to extremely channery silt loam; inherited thin platy structure; firm; 75 percent rock fragments; slightly acid; abrupt wavy boundary. (2 to 30 inches thick)
R--51 inches; hard phyllite bedrock.
TYPE LOCATION: Montgomery County, Maryland; 1 mile SW of Lewisdale; 4200 feet S on Clarksburg Road from its intersection with Lewisdale Road, 50 feet E into field.
39 degrees 16'22" N; 77 degrees 16'34" W.
RANGE IN CHARACTERISTICS: The thickness of the solum ranges from 20 to 40 inches. Depth to bedrock or paralithic contact is 22 to 58 inches. Rock fragment content of micaceous schist and phyllite ranges from 20 to 50 percent by volume in the A horizon and from 35 to 75 percent by volume in the B and C horizons. Some pedons contain angular gravels and cobbles of quartzite or up to 15 percent stones of schist or phyllite. Reaction is strongly acid to neutral.
The Ap or A horizon has hue of 10YR or 2.5Y, value of 3 to 5 and chroma of 1 to 4; value of 3 is confined to A horizons. It is silt loam or loam in the fine-earth fraction. Uncultivated areas may have an E horizon.
The B horizon has hue of 7.5YR to 5Y, value of 4 to 6 and chroma of 4 to 8. It is silt loam, silty clay loam, or clay loam in the fine earth fraction.
The BC horizon has hue of 7.5YR to 5Y, value of 4 to 6 and chroma of 4 to 8, but may be as low as 2. It is silt loam, silty clay loam, or clay loam in the fine earth fraction.
The C horizon has hue 0f 7.5YR to 2.5Y, value of 4 to 6, an chroma of 2 through 8. It is silt loam or silty clay loam, or clay loam in the fine earth fraction.
COMPETING SERIES: The Neotoma series is in the same family. Neotoma soils have rock fragments dominated by siltstone or sandstone. The Brandywine, Cardiff, Mt. Airy, and Skalan series are similar soils in related families. Brandywine soils have sandy-skeletal particle-size control sections and contain coarse fragments of gneiss. The Cardiff and Mt. Airy soils have cambic horizons. The Skalan soils have a xeric moisture regime.
GEOGRAPHIC SETTING: Linganore soils are on nearly level to steep soils on crests and slopes of elevated, usually steep ridges. They formed in residuum from micaceous schist, phyllite, and slate. Slopes range from 0 to 55 percent but generally are between 3 and 25 percent. The climate is temperate and humid, with a mean annual temperature of 50 to 55 degrees F. and mean annual precipitation of 40 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Baile, Cardiff, Chester, Glenelg, Glenville, Mt. Airy, and Urbana soils, none of which has a skeletal particle-size control section. Baile soils are poorly drained and are on upland depressions and footslopes. Cardiff, Chester, Glenelg, and Mt. Airy soils are in similar positions on the landscape as the Linganore soils. Chester soils do not have bedrock within a depth of 40 inches. Glenelg soils have less than 35 percent base saturation. Glenville and Urbana soils have fragipans and are on upland flats, sideslopes, and footslopes.
DRAINAGE AND PERMEABILITY: Well drained and somewhat excessively drained. Permeability is moderate in the solum and moderate to moderately rapid in the C horizon. Runoff is slow to very rapid depending on slope.
USE AND VEGETATION: Used for general crops, pastures, and orchards. The native vegetation includes black oak, Virginia pine, yellow poplar, and black locust.
DISTRIBUTION AND EXTENT: Maryland and possibly Virginia (Major Land Resource Area 148). The series is of moderate extent.

REMARKS: Diagnostic horizons and features recognized in this pedon are:
a. Ochric epipedon - The zone from the surface of the soil to a depth of approximately 11 inches (Ap1 and Ap2 horizons).
b. Argillic horizon - The zone from approximately 11 to 17 inches (Bt horizon).
c. Ultic udalfs feature - base saturation (by sum of cations) of less than 60 percent immediately above the lithic or paralithic contact.
