Shoreline changes of Navarino Bay. Late Helladic palaeogeographic reconstructions of the Nava-rino embayment, roughly 3500 years before the present. The map depicts known Helladic ar-chaeological sites. Ancient sea cliffs are linked to Neolithic (5000 B.P.) and Mesolithic (9000 B.P.) shoreline reconstructions. On the north flank of Coryphasium, one neolithic site is indicated [Source: Kraft, 1980].
