Lake Arkona-Whittlesey and Post-Warren Radiocarbon Dates from "Ridgetown Island" in Southwestern Ontario
Three radiocarbon dates from raised beaches along the "Ridgetown Island" support the age assignment of 13,000 years B.P. for the beginning of Lake Whittlesey in Ohio, and the termination of Lake Warren before 12,000 years B.P., as concluded from post-Warren data in Ontario.
