The charcoal was submitted by Robert Funk to Isotopes, Inc. in October, 1966. Thus, based on both absolute and relative (stratigraphic) chronological data, the River complex occupied a time period intermediate between the Sylvan Lake complex, dated 2210 B.C. in the lower Hudson Valley (Funk 1966a; 1966b; Funk, Weinman, and Weinman 1965) and the Snook Kill complex, dated 1470 B.C, at the type site in the upper Hudson Valley (Ritchie 1965:135). The Pickle Hill component is the first reported River complex manifestation which is not located on a major waterway. Its small size indicates that it was a seasonal camp site, visited by small bands of people, perhaps over a relatively brief period of years. The darkened area, seen from the air, may represent the traces of a single family lodge. All evidence points to the conclusion that Pickle Hill was occupied in fall and winter, when acorncollecting and hunting were the main subsistence activities.
