Mean annual temperature ranges from 53 to 59 degrees F. and the mean annual precipitation ranges from 40 to 49 inches. These are the Berks , Dekalb , Gilpin , Jefferson , Kimper , Latham , Marrowbone , Muskingum , Pineville , Sharondale , and Shelocta series. Berks, Dekalb, Gilpin, Latham, and Muskingum soils are on nose slopes and ridge crests, are formed over dominantly residual material, and are moderately deep to rock. Kimper soils are commonly on north and east facing slopes, have a thicker or darker epipedon, and are fine-loamy. Sharondale soils are in deep coves of north and east facing slopes, have a mollic epipedon, and are loamy-skeletal.
Marrowbone soils are on lower side slopes and are moderately deep.
Jefferson, Pineville, and Shelocta soils are on lower lying landscapes of smaller, less sloping mountains and have an argillic horizon. In addition, Jefferson soils are siliceous. Runoff is slow to very rapid. Permeability is moderately rapid in the solum and moderate or moderately rapid in the C horzon. Most areas are in second growth forest with mixed stands of white oak, American Beech, mockernut hickory, pignut hickory, black oak, sugar maple, sassafrass, red maple, chestnut oak, Virginia pine, and flowering dogwood.
