- Comments
- Kipp Island: This site is located on the Seneca River on a landform rising above Montezuma's Marsh north of Cayuga Lake. It is the type site of Ritchie's Middle Woodland Kipp Island phase, although it also produced other components. Hart et al. (2003) present 11 AMS dates on cooking residues from pottery vessel interiors. The dates fall into two groups that approximately correspond to Ritchie's Hunter's Home and Kipp Island phases, respectively. Phytoliths recovered from the residues indicate that the pots were used to cook maize, wild rice, squash, and a tuberous sedge.
