As Saturday was a rough weather day the team combed the Martinhal beach in search of stones similar to those seen on the sea floor. In the past, the beach served as a river mouth, and river stones are found scattered across and within the sand during the groundtruthing surveys. As expected, the same types of stone were found on the beach. In addition, vestiges of Roman kilns could be seen on the beach’s cliff face. With the stormy weather conditions, it is easy to see how Diaz’s vessel could have wrecked in the bay.
