[Various (1967)] But what is represented does exist in the concrete form of archaeological specimens. The model here given is certainly subject to revision and amendment. DISCUSSION Ritchie, in his definitive volume The Archaeology of New York State (1965) has inferred that he no longer regards the 5383 ± 250 C14 date released by Libby in 1950 as the cornerstone date for the Northeastern Archaic that it was once considered to be, and it no longer seems to date the Lamoka culture characterized by, among other traits, narrow-bladed stemmed and side-notched points found at the type site at Lamoka Lake. This early date has become suspect because later re-testing of charcoal from the original dig, by the advanced gas diffusion method, which replaced the solid carbon method, produced ages of the order of 4500 years. This order of age was corroborated by a serie s of tests run on charcoal obtained by later re-excavations of the site (1958, 1962) best summarized by the Yale C14 Laboratory result of 4500 ± 80 B.P. (Y-1279). Excavations by Funk (1966:18) at the Sylvan Lake Rockshelter in 1964-65 yielded a series of narrowbladed, stemmed, small points, described by him as Lamoka-like and Bare Island-like, with intermediate forms, which were dated at 4160 ± 140 (Y-1536). Ritchie's work at Martha's Vineyard in 1964-65 (1966:901) produced a date on narrow-bladed, stemmed, small points, designated Wading River points by him, of 4220 ± 160 (Y-1530).
