Gardiner’s and Peconic Bays froze solid at least a few times in the last century, such that foxes and deer were able to walk across the ice from one island or one mainland to the other. Large portions of the Great South Bay freeze over once every three or four winters, such that the iceboats come out and sail back and forth at speeds exceeding 20 miles per hour. The frozen tops of Noyac Bay and Three Mile Harbor have also been skimmed by iceboats several times in the last century.
