St Martins in New Brunswick, on the Bay of Fundy coast in Canada, is famous for its red Triassic cliffs. These have been eroded by the sea to form large caves in which seals like to rest. The adjacent long beach is composed of millions of pebbles or beach stones from not only the nearby Triassic strata but also brought down from far and wide by the massive ice sheets that once covered the land mass. There is an amazing variety of rock types represented by the pebbles, with red and green colours most noticeable, and many textures and patterns exhibited.
