Coulbourn is a late Early to early Middle Woodland
ware, characterized by a temper of clay nodules or fragments,
and cord-marked or net-impressed exterior surface treatments.
Defined types include Coulbourn Cord-Marked and Coulbourn Net-Impressed.
Stratigraphic sequences and radiometric dating
indicate that Coulbourn dates from ca. 500 B.C. – A.D. 1.
Coulbourn is found primarily along the Delaware Bay and Atlantic
Coast drainages, as well as on the southern Delmarva Peninsula,
in Kent and Sussex counties. It has also been found in the Upper
Eastern Shore region of Maryland.
The temper consists of inclusions of fired clay or crushed ceramic
Exterior surfaces are cord-marked or net-impressed. Griffith and
Artusy (1977:15) noted that the orientation of cord-marking on
sherds recovered from the Wolfe Neck site is most commonly perpendicular
to oblique, but also includes horizontal marks or a combination
of the three styles. A combination of horizontal and perpendicular
marks is the norm on Coulbourn Net-Impressed sherds. Interior
surfaces range from scraped-over cord or net impressed, totally
scraped, smoothed-over scraped, to completely smooth. The most
commonly encountered treatment is scraped.
Coulbourn is coil-constructed with paddle malleation. Vessels
have a conoidal shape, with direct rims. Lips are flattened, rounded,
and mostly smooth, but some have been found with net or cord impressions.
Vessel wall thickness ranges from 7 mm – 14 mm, with a mean of
10 mm. Vessel walls are thick and uneven.
Defined in the Literature. Coulbourn is an Adena Complex ceramic. Custer (1984) and Griffith
and Artusy (1977) have noted similarities to Wolfe Neck and Popes
Maryland Sites with Coulbourn components
