Abstract
A peat deposit exposed in a wave-cut cliff on the island of Martha9s Vineyard, Massachusetts (31 degrees 259N., 70 degrees 309W.), has been sampled for radiocarbon and pollen content. The section is 2.29 m long, including 12 cm of till at the base. The deposit is overlain by 30 to 50 cm of windblown sand, and the upper 25 cm of the peat is weathered and oxidized. The till at the base of the section contains randomly oriented pebbles overlying stratified till. Pollen studies indicate that much of the pollen in the till is primary. The pollen stratigraphy of the sediments overlying the till is similar to the pollen sequence of core MV-7 in Duarte9s Bog. Four radiocarbon dates from clay gyttja at the base of the deposit show radiocarbon ages from 12,300 to 12,700 B. P. The base of the deposit is, therefore, chronologically equivalent to the A1 pollen zones of southeastern Connecticut. Correlation of the Squibnocket pollen sequence with that from core MV-7, though possible even in details, is now believed to imply nothing more than a late-glacial ecology and date for pollen zone V; the further inference that V must be older than T (at Totoket, Connecticut) is abandoned. If V and T are contemporary, however, several correlations of glacial substages in southern New England are shown to be probably incorrect, and the moraines on Cape Cod may be of Port Huron age.
