TYPE LOCATION: Adams County, Pennsylvania; Freedom Township, 5 miles southwest of Gettysburg, just north of Route T327, 1/8 mile west of intersection with Township Route 328.
RANGE IN CHARACTERISTICS: Solum thickness ranges from 12 to 24 inches. Depth to bedrock ranges from 20 to 40 inches. Rock fragments of shale range from 2 to 30 percent in the Ap horizon, 2 to 45 percent in the Bt horizon, and from 30 to 90 percent in the C horizon; the weighted average is less than 35 percent by volume in the particle-size control section. Where unlimed, the solum ranges from very strongly acid through slightly acid. Illite is the dominant clay mineral, but the soil contains small amounts of kaolinite, vermiculite, and interstratified minerals.
The Ap horizon has hue of 2.5YR through 7.5YR, value of 3 or 4, and chroma of 2 through 4. Texture is silt loam in the fine-earth fraction.
The B horizon has hue of 10R through 5YR, value of 4 through 6, and chroma of 3 or 4. It has redoximorphic features with hue of 2.5YR or 5YR, value of 5 or 6, and chroma of 2 through 8. Texture is silt loam or silty clay loam in the fine-earth fraction.
The C horizon has hue of 10R to 5YR, value of 3 to 4 and chroma of 2 to 4. Fine earth texture is silt loam, loam or silty clay loam.
COMPETING SERIES: The Bogart, Centerburg, Cygnet, Haney, Houchtown, Jenera, Jugtown, Nicely, Scattersville, Swampoodle, Thackery, Tuscola, Vanlue, and Willimaston series are in the same family and all are greater than 40 inches to bedrock. Bogart soils have more than 15 percent rock fragments in the middle part of the series control section. Centerburg soils have lithic contact below 60 inches. Cygnet and Jenera soils have more than 25 percent clay in the lower part of the series control section. Haney and Thackery soils average more than 15 percent rock fragments in the lower part of the series control section. Houcktown soils have a densic contact within 60 inches. Jugtown soils are more alkaline than moderately acid in the upper part of the argillic horizon. Nicely soils are deeper than 50 inches to the base of the argillic horizon. Tuscola soils are stratified in the lower part of the series control section. Vanlue soils have less than 2 percent rock fragments in the lower part of the argillic horizon. Williamstown soils have rock fragments of dominantly limestone and crystalline lithology. Scattersville soils formed in mountain colluvium (solifluctate) from mixed basic and acidic rock materials in swales, broad interfluves, and on mountain footslopes at the base of the Blue Ridge. Swampoodle soils formed in local colluvium over residuum derived from greenstone schist, biotite schist, and basic gneiss. Swampoodle soils are more acid than neutral in the lower part of the series control section. Conowingo, Lehigh, Mount Lucas, Vaughnsville soils are family related soils.
GEOGRAPHIC SETTING: Reaville soils are on interfluves with very little dissection. Slope ranges from 0 to 15 percent. The soil formed in residuum weathered from red interbedded, Triassic shale, siltstone, and fine- grained sandstone. The climate is humid and temperate; mean annual precipitation ranges from 40 to 46 inches, mean annual temperature ranges from 50 to 60 degrees F., and the growing season ranges from 150 to 200 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These include the Abbottstown, Croton, Klinesville, Lansdale, Penn, Readington and Teas series. Abbottstown and Readington soils have a fragipan and are more than 40 inches to bedrock. Croton soils have dominant chroma of 2 or less immediately below the Ap horizon. Klinesville soils have bedrock within 20 inches of the soil surface. Lansdale, Penn, and Teas soils do not have low chroma redox in the upper argillic horizon.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Moderately well and somewhat poorly drained. Surface runoff is medium to slow. Saturated hydraulic conductivity is moderately low.
USE AND VEGETATION: Mostly cleared and cultivated. Hay, small grain, and corn are the principal crops, and some areas are in pasture. General farming and dairy farming are the main enterprises. Portions of the area have been utilized for Urban development.
The native vegetation was mixed hardwoods, predominantly oaks.
DISTRIBUTION AND EXTENT: Southeastern Pennsylvania, New Jersey, Maryland, and Virginia. The series is of moderate extent.
