Calanque de Sugiton

This guide to Calanque de Sugiton in Marseille traces the pale limestone underfoot back roughly 130 million years, when this stretch of Provence sat beneath a warm, coral-filled sea. It follows the collision of Africa and Europe that buckled the seabed upward, and the ice ages that carved deep valleys through the exposed rock as sea level dropped. Look for fossilized sea creatures in the broken rock, and for the offshore islet locals call the torpedo boat.
