Comments
AdHq-VP, Muirkirk: Two mammoth locations are on the Ridgetown Island Moraine which was submerged by Lake Whittlesey but exposed above subsequent Lake Warren. Both finds probably date to after 12,700 years BP, but Beta-17869 and Beta-115209, on one of them, are considered to be anomalously young.
