A fragment of an oddly sculptured glass disc found on the cliff of Gay Head, on Martha's Vineyard, Massachusetts, is thought to be a tektite. Unless carried to Gay Head by man from one of the known tektite fields, it raises to three the number of tektite localities in the Western Hemisphere. The freshness of surface features and the clarity of glass indicate a recent origin. If, however, it weathered out of the cliff, it may be Late Cretaceous, Miocene, or Pleistocene in age. © 1961, The Geological Society of America, Inc.
