The sea caves at St. Martins are formed in the Triassic Honeycomb Point Formation. These rocks are about 250 million years old. They’re overlain by the bouldery conglomerate of the Quaco Formation. Both these sediments were laid down in rivers and alluvial fans into a rift valley that was part of the opening of the Atlantic Ocean.
