[Various (1967)] Since Ritchie has a date of 4474 ± 300 (Ritchie 1965:91) on a Vosburgian phase hearth at the Bannerman site in Dutchess County and Funk has the aforementioned date of 4220 ± 160 on a narrow -bladed, stemmed point level at Sylvan Lake Rockshelter, also in Dutchess County, it would appear that the Taconic and Laurentian traditions were contemporaneous in the Hudson Valley, probably through several centuries, since the Brewerton phase of the Laurentian is given a "climax" date by Ritchie (1965:91) of about 4000 B. P. Thus the acculturation of the Lamoka focus people of the Taconic tradition of point makers and the Laurentian tradition as posited by Ritchie at the Frontenac Island site is inherently probable. Likewise inherently probable is the acculturation of the two traditions over the whole Northeast. By the known dates the Taconic tradition is a late but fully Archaic cultural strain. Because its earliest acceptable date of record is at the Twombly site, its origin is enigmatic. Wauchope's extensive collection of "stemmed narrow blades" was obtained during an archaeological survey of Georgia in WPA days, that is the 1930's, but were only this year (1966) published in a Memoir of The Society for American Archaeology. He says that they "probably appeared in the Archaic" and apparently continued into the Woodland periods.
