Deerfield and Klej soils are moderately well drained on lower, concave positions. Haven and Riverhead soils have a loamy subsoil and commonly occur on less sloping landforms. Montauk soils have firm gravelly substrata. Eastchop is geologically intermingled in moraine areas with till soils, Montauk and Plymouth. Runoff is slow.
Permeability is rapid or very rapid.
Most of the soil is in woodland. A few areas are cropped. Trees include white oak, black oak, pitch pine, and locust. The soil is of small extent. Dukes County, Massachusetts, 1983.
