MINE RUN SERIES
The Mine Run series consists of moderately deep, somewhat excessively well drained soils formed in metamonzonite and gneiss in the Northern Piedmont. Permeability is moderately rapid. Slope ranges from 3 to 45 percent. Mean annual precipitation is about 43 inches, and mean annual air temperature is about 56 degrees F.

COMPETING SERIES:
Bannertown,
Cheshire,
Devotion,
Ditney,
Fedscreek,
Marrowbone,
Maymead and
Tipsaw are in the same family. Bannertown soils develop in residuum of granite in MLRA 136. NOTE: IF BANNERTOWN CAN BE EXTENDED TO MLRA 148, THERE IS NO NEED FOR MINE RUN SERIES. Cheshire soils are very deep to bedrock and develop in glacial till. Devotion soils are greater than 40 inches to lithic contact and develop in residuum of granite and gneiss in MLRA 136. Ditney soils develop in residuum of metasediments of the Blue
Ridge Mountains. Fedscreek soils are deep to bedrock and develop in colluvium of sandstone, siltstone and shale. Marrowbone soils develop in colluvium and residuum of sandstone and siltstone. Maymead soils are very deep to bedrock and develop in colluvium. Tipsaw soils develop in residuum of interbedded sandstone and siltstone.

GEOGRAPHIC SETTING: Mine Run soils formed in residuum from metamonzonite and gneiss in the Northern Piedmont. Mine Run soils are on summits, shoulders, and backslopes of side slopes, head slopes and nose slopes of ridges. Slope gradients range from 0 to 45 percent. Mean annual air temperature 55.7 degrees F., with average winter temperature of 35.4 degrees F and average summer temperature of 74.6 degrees F. Mean annual precipitation ranges from 36.47 to 48.39 inches, frost free days range from 237 to 185 days, and elevation ranges from 100 feet to 400 feet above sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Penhook (tentative),
Yellowbottom (tentative),
Happyland (tentative),
Goldvein,
Blocktown, and
Drapermill soils. The well drained Penhook, Yellowbottom (tentative) and Happyland (tentative) soils are on adjacent summits, shoulders and less steep sideslopes. The moderately well drained Goldvein soils are on summits and shoulders of sideslopes and headslopes. The well drained Blocktown and Drapermill soils are on similar landscape positions.
DRAINAGE AND PERMEABILITY: Somewhat excessively well drained. The potential for surface runoff potential is medium. Permeability is moderately rapid. In undisturbed areas the depth to the top of an apparent seasonal high water table is greater than 60 inches in most years.
USE AND VEGETATION: Soils are mainly in woodlands. Native vegetation is mixed hardwoods, but much has been harvested and replanted to pine.
DISTRIBUTION AND EXTENT: MLRA 136 (mesic) and 148. The soils are of small extent.
