During September of 1958 M. B. McKusick and C. N. Warren conducted archaeological excavations on San Clemente Island, California. In 1959 the result of their work was published. They delineate three cultural complexes for the island which are named “Milling Stone,” “Mortar and Pestle,” and “Big Dog.” The data presented by McKusick and Warren are examined and their three cultural complexes are rejected because these complexes are not adequately supported by the data.
