“Beachrock” at the western entrance to the Corinth canal, covering the loading platform of the diolkos road. The authors of the Lechaion tsunami theory (discussed yesterday) have suggested this rock represents “calcified tsunamigenic deposit” caused by a tsunami sometime after the first century AD (Hadler et al. 2011, p. 72). The beachrock runs 300 m inland in this area. Photo D. Pettegrew, June 1, 2011.
