Abstract: Most harbors and bays in northern Long Island are subglacial tunnel valleys formed during the Last Glacial Advance about 21,000 years ago. Stumm and others in several publications and Smolensky, 1990 have delineated older valleys filled with sediment underlying Long Island which are probably also subglacial tunnel valleys.
