A sample of salt‐marsh peat from a depth of 59 m at the northwestern margin of Georges Bank has a radiocarbon age of 11,000 ± 350 years. No greater depth or age of salt‐marsh peat lying exposed on the ocean floor elsewhere in the world are known to the authors. The age corresponds well with the date of ice retreat from the Gulf of Maine and with the ages of oyster and other shells that mark the advance of the ocean across the bank and the adjacent continental shelf.
