There he goes again;according to Larry Furo “I know a 100 or more metal detectors & watch all the detector sites & nothing ever comes up from the bronze age here...only Old Copper Complex & Mississippian/Adena.” As I keep pointing out to Larry and others on this site, widely respected scholars like Alice Kehoe have documented numerous similarities between the Adena and Bronze Age cultures from northern Europe, including pottery and burial practices.
A widely used textbook(Ancient Native Americans) by the former President of the Society for American Archaeology, Dr. Jesse Jennings, includes a long chapter by the diffusionist scholar Stephen Jett (a retired Department Chairman and professor of Geography at the University of California Davis” Jett summarized anthropologist Alice Kehoe’s work comparing the American mound builders (the Hopewell and Adena cultures) to cultures in northern Europe where the Bronze Age trading system was linked to Egypt and Greece:
Extra-continental origins have been posited for North American ceramics. The earliest known Woodland pottery of the Northeast is often said to have been diffused from Siberia, although it does not occur west of the Great Lakes region. Neither does it appear to derive from Formative wares of the southeast, although some have proposed a Mesoamerican origin. Kehoe pointed out that Vinette 1 pottery appeared without antecedents prior to 1000 BC in New York state and adjacent Canada and in most respects is very similar to the contemporary pottery of Norway, which has a long evolutionary history…Traits shared at this period include gouges, adzed plummets, ground-slated points and knives, barbed bone points, and chipped stone projectile points.
Vinette 2 pottery is reminiscent of wares of the contemporaneous western European maritime Bell Beaker cultures. Kehoe further suggested that European funerary practices, including barrow building, may be reflected in the use of burial mounds during the Early and Middle Woodland of about 1100—500 BC. The latter period includes the Hopewell culture of the Midwest, in which a number of ceramic traits have European parallels… Huscher has argued for North American linguistic borrowing from the Baltic region. The sweat bath could also represent a transatlantic transfer.”(at 564)
The mounds built in the Nordic countries during this period bear a remarkable resemblance to those found among the Adena and Hopewell cultures, and may be linked to a European people called the Bell Beakers, who were known to be prospectors for copper. According to Dr. Kehoe, the “characteristic bell-beaker grave is a stone cist under a round ‘barrow,’ in which male burials were accompanied by a copper knife, arrows (with heads of flint, tanged-and-barbed or concave-based), and a perforated polished stone plaque interpreted as an archer’s wrist guard. Often included also buttons, carved bone pins with ribbed heads, and tubular copper beads.”
It is possible, she says, that “Woodland burial mounds, with the bodies in cists and accompanied by ceremonial ‘mortuary’ blades, bar gorgets that could be functionless wrist guards, copper beads, etc., may have been derived from Europe.” (A Hypothesis on the Origin of Northeastern American Pottery, Southwestern Journal of Anthropology, vol. 18, 1962 at 27)
Kehoe says the Scandinavian middens have abundant cod bones, and that cod fishing could only be accomplished by venturing into the high seas in their skin curraghs, which she believes were capable of sailing west along the Irminger Current to Iceland, Greenland and the Americas, the same path as followed by the later Vikings.
[Basically we have the situation that the Old Copper Culture and associated cultures of North America were contemporaneous with Bronze Age Europe and made tools of similar design, and that the Adenas and Hopewell "Mound Builders" were continuances of the same peoples after about 1500 BC and the end of both the Old Copper Culture and the European Bronze Age. The European Megalithic period was characterized by two kinds of mounds associated with two distinctive ethnic groups, the tall roundheads that made conical mounds and the short longheads that made mounds of different types (typically the long barrows but also the effigy mounds in North America) Both peoples were actually transatlantic in origin and distribution. Barry Fell touched on this and his book Bronze Age America deals with the period of the Old Copper Culture while America BC talks about the persisting Megalithic-derived cultures in the American side. The DNA of both sets of peoples tends to go along with this interpretation. The R1 Y-DNA groups are primarily the longheaded population on either side of the ocean-DD]
