|Colin says: North Scar - Earnse Bay.|
Such "scars" were deposited during the last ice age and can be found all along the lowest extremities of Walney Island's western beaches. The pebbles average out at around 5 or 6" long and are partly embedded in the till shore platform, although this is rarely exposed. Occasional large boulders (known as "erratics") up to one metre diameter or even more can be found. The scars probably indicate the extent of former drumlins which were eroded to leave only the coarsest material which cannot easily be moved by prevailing waves and tides.
