The Glamorgan Heritage Coast of South Wales, U.K., formed millions of years ago when present day Wales was nearly completely submerged. These exposed, eroded early Lower Lias or early Jurassic rocks, primarily limestone and shale, are readily accessible to rock hounds and to people who simply enjoy strolling along the shore. The beach platforms, cliffs and sea caves (like this one) here are all quite spectacular both when viewed from the cliff-top paths and when exploring up close. Make sure to consult tidal charts before investigating the sea caves since this portion of the Welsh coast has a considerable tidal range - over 50 ft (16 m). Photo taken on July 20, 2011.
