Permian

Even after 290 million years of erosion, some rocks deposited by the ice-sheet can still be found. They are mostly an odd mixture of pebbles and boulders suspended in consolidated sand and mud. Some very large blocks left behind by the ice-sheet are called ‘erratics’ because they are unlike any local rocks.
