Pickering Beck is a river that runs for over 18 miles (29 km) from its source in the North York Moors National Park through the town of Pickering and on to its confluence with Costa Beck at Kirby Misperton. It is a meandering river that is fed by numerous named and unnamed becks and streams which flow over sandstone and limestone beds and an alluvia of sand, clay silt and gravel. The beck is known for flooding and in recent times has been a beneficiary of funding and experimental flood protection schemes.
