The regolith consists of 5 to 15 inches of loess over 10 to 30 inches of clayey residuum overlying loamy-skeletal colluvium derived from dolomite. Mean annual temperature ranges from 42 to 50 degrees F, and mean annual precipitation ranges from 28 to 35 inches. These are the Blackhammer , Dorerton , Lacrescent , Nodine , Newhouse , Rollingstone , Seaton , Southridge , and Valton soils. Blackhammer, Nodine, Newhouse, Rollingstone, Southridge, and Valton soils are upslope with lesser gradient and contain less rock fragments. Dorerton soils are on positions similar to Lamoille soils, but they have loamy-skeletal argillic horizons.
Lacrescent soils have a mollic epipedon have steeper slopes and typically are downslope.
Seaton soils are upslope and formed in thick loess. Runoff is rapid or very rapid. Permeability is very slow and slow in the 2B horizon and moderate and moderately rapid in the 3C horizon. Most areas are in woodland or pasture. A few small areas are cultivated with legume hay and small grain being the principal crops.
