The competing Deerfield , Eastchop , Plymouth and Windsor soils often are on adjacent landscapes. The organic Freetown and Swansea soils and the very poorly drained Scarboro soils are in the kettleholes of the pitted outwash plains and the Gloucester and Montauk soils are intermingled on moraines. The Merrimac and Haven soils, which contain more silt, and the loamy Riverhead soils are on plains adjacent to the moraines. Carver is the excessively drained member of a drainage sequence which includes the moderately well drained Deerfield, somewhat poorly drained Saugatuck and Pipestone soils, and the very poorly drained Berryland soils. Runoff is very slow.
Permeability is very rapid.
Mostly forested to scrub oak, pitch pine and white pine. A small part is cleared and cropped. The soil is extensive, estimated 110,000 acres. This soil was previously classified as siliceous, mesic Typic Udisamments. Lab data indicates by far the majority of Carver soils have more than 90 percent minerals resistant to weathering.
