This picture was taken at Bandon beach, Oregon. Bandon is well-known for its memorable seascape of stacks of all shapes and sizes. These rock formations are known to geologists as ‘knockers’ and carry nicknames like ‘the Wizards hat’. They date from the Jurassic period – about 200 to 145 million years ago – and are what remains from the great mélange during tectonic subduction processe ...[Read More]
