Latt. 39 36' 39" Long. 77 40' 19"
RANGE IN CHARACTERISTICS: Solum thickness ranges from 40 to 60 inches. The A horizon ranges from 8 to 15 inches thick, but can range up to 22 inches thick in some places. Lithic contact is greater then 72 inches. Depth to underlaying residuum ranges from 25 to 60 inches. Depth to the top of the argillic is above 40 inches. Rock fragments composed of chert, quartzitic sandstone, and limestone gravel range from 0 to 25 percent in the Ap horizon, and 10 to 60 percent in individual subhorizons of the Bt and Bw horizon, but averages to be less than 35 percent. The 2Bt and 2C horizon has rock fragments of predominantly limestone which range from 5 to 25 percent. The reaction ranges from moderately acid to slightly alkaline throughout the profile.
The Ap horizon has hue of 7.5YR, through 10YR value of 3 through 5, and chroma of 3 through 6. Texture in the fine earth fraction is silt loam, loam, or silty clay loam. Reaction ranges from slightly acid to slightly alkaline.
The BE horizon has hue of 7.5YR through 10YR, value of 3 through 6, and chroma of 3 through 6. Texture in the fine earth fraction is silt loam, loam, or silty clay loam. Reaction ranges from slightly acid to neutral.
The Bt and Bw horizon has hue of 5YR through 10YR , value of 4 through 6, and chroma of 4 through 8. Texture in the fine earth fraction is silty clay loam, clay loam, loam, or silt loam. Reaction ranges from slightly acid to neutral.
The 2Bt horizon where present has hue of 5YR through 7.5YR, value of 4 through 8, and chroma of 4 through 8. Texture in the fine earth fraction is commonly silt loam, loam, or clay loam, but also includes in some pedons silty clay, silty clay loam and clay. Reaction ranges from moderately acid to neutral.
The 2C horizon has hue of 5YR through 2.5Y, value of 4 through 8, and chroma of 4 through 8. Texture in the fine earth fraction is commonly silt loam, loam, or clay loam, but also includes in some pedons silty clay, silty clay loam and clay. Reaction ranges from moderately acid to neutral.
COMPETING SERIES: Hennepin is the only known soil in the same family. Lindside and Weaver soils are in closely related families. Lindside contains less than 15 percent sand in the particle size control section. Weaver has an irregular decrease in organic carbon.
GEOGRAPHIC SETTING: Funkstown soils occupy upland draws and head slope positions. Slopes range from 0 to 3 percent. Funkstown soils formed in colluvial and alluvial material washed from surrounding upland soils, over limestone residuum. Mean annual precipitation ranges from 38 to 50 inches, and mean annual air temperature ranges from 51 to 53 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Dunning, Huntington, Lindside, Melvin, Timberville, and Warners soils. The Dunning, Huntington, Melvin, and Warners soils have a mollic epipedon. Lindside contains less than 15 percent sand in the particle size control section. Timberville soils contain more than 35 percent clay in the particle size control section.
DRAINAGE AND PERMEABILITY: Moderately well drained. Runoff is slow. Permeability is moderate.
USE AND VEGETATING: Most areas are in crops or pasture. In urban settings, they are in waterways or open spaces.
DISTRIBUTION AND EXTENT: Maryland, Virginia, West Virginia, Pennsylvania. Total extent is moderate.
