Native Americans began moving into New England after the retreat of the Wisconsin Glacier, around 12,000 BC. Artifacts discovered at Great Neck and along the riverbanks have been identified as belonging to the later Archaic period (8000-5000 years ago) and the Woodland period (2000 years ago). Evidence of a 3000-year old village was discovered along the Merrimack River in West Newbury.
Native Americans grouped in tribes and moved seasonally for agriculture, fishing and hunting. By the 1500′s, all of the many New England tribes shared the Algonquian language, with varying dialects, but they did not develop a written language. Within a century of the arrival of European settlers, our American Indian predecessors and almost all evidence of their existence had vanished.
In September 1882, Mr. I. J. Potter of the Ipswich Chronicle discovered a 100′ x 60′ shell heap on Perkins (Treadwell’s) Island that had never been disturbed. Its contents included crude stone points and knives, and human bones broken in a manner that suggested ritual cannibalism.
At about the same time, behind what is now Lane’s Farm on High Street, a plowshare uncovered a cache of forty finely-fashioned stone spearheads. A half mile behind that site, in the early 1950′s, a group of young amateur archeologists men now known as the “Bull Brook Boys” discovered one of the largest Paleo-Indian sites in North America along the banks of Bull Brook and the Egypt River in an area being cleared for a sand and gravel operation. Over 6,000 artifacts were uncovered in a large circle about the size of four football fields, and are on display at the Peabody Essex Museum in Salem. Two more discoveries were made in the late 1960′s, but the site is now a gravel pit.
Radiocarbon dating at Bull Brook places the settlement at around 10 – 11,000 years ago, during or just after the cold Younger Dryas period. Glaciers had receded from the North Shore area but sea level was still low enough that the Bull Brook site would have been about ten miles from the coast. Calcified remains of caribou and the constricted valley of the Eagle River suggest that the location may have been ideal for drive-hunting.
While new discoveries in central Texas push the arrival date of Paleoindians back to over 15,00 years ago, the Bull Brook site provides some of the oldest physical evidence for large-scale Paleoindian gatherings in North America.
