Cataska and Unicoi soils are shallow and skeletal. Ditney and Maymead soils do not have an argillic horizon and are in a coarse-loamy family. Jeffrey soils have a dark suface layer 7 to 10 inches thick. Junaluska and Soco soils have a paralithic contact at 20 to 40 inches and lack a lithic contact within 20 to 40 inches. Keener, Lostcove, and Northcove soils are very deep and formed in colluvium.
Principle use is woodland.
Much of the acreage is owned by the U.S. Forest Service. Native forest has upland oaks, hickory, dogwood, elm, shortleaf pine, Virginia pine, or white pine. The series is of small extent. McCamy soils were previously included in the Ditney or Soco series. McCamy and Lily soils are similar.
