Doom Bar

Sandbar at the mouth of the River Camel, Cornwall, England

The Doom Bar is a sandbar at the mouth of the estuary of the River Camel, where it meets the Atlantic Ocean on the north coast of Cornwall, England. Like two other permanent sandbanks further up the estuary, the Doom Bar is composed mainly of marine sand that is continually being carried up from the seabed. More than 60 percent of the sand is derived from marine shells, making it an important source of agricultural lime, which has been collected for hundreds of years; an estimated 10 million tons of sand or more has been removed from the estuary since the early nineteenth century, mainly by dredging.
