Flamborough Head

Flamborough Head

Flamborough Head in the East Riding of Yorkshire

The headland is the only chalk sea cliff in the north. The coastline within the SSSI has strata from the upper Jurassic through to top of the Cretaceous period, and the headland exhibits a complete sequence of Chalk Group North Sea Basin strata, dated from 100 to 70 million years ago. The various chalk deposits are known as the Ferriby, Welton, Burnham and Flamborough Chalk.[7] The dramatic white cliffs contrast with the low coast of Holderness to the south, where the chalk is deeply buried and the glacial boulder clay above erodes very readily.[8] The chalk cliffs have a larger number and a wider range of cave habitats at Flamborough than at any other chalk site in Britain, the largest of which are known to extend for more than 50 metres from their entrance on the coast. There are also stacks, natural arches and blowholes. The site is identified as being of international importance in the Geological Conservation Review.[7]

Kittiwakes (Rissa tridactyla) on the chalk cliffs at Flamborough Head

Seabirds such as northern gannets, kittiwakes and Atlantic puffins breed abundantly on the cliffs.[7] Bempton Cliffs, on the north side of the headland, has an RSPB reserve and visitor centre.[9]

The shooting of seabirds at Flamborough Head was condemned by Professor Alfred Newton in his 1868 speech to the British Association for the Advancement of Science. Local MP Christopher Sykes introduced the Sea Birds Preservation Act 1869, the first Act to protect wild birds in the United Kingdom.[10] Shooting continued, with an 1886 edition of The Cornishman newspaper reporting the enormous flocks of sea birds are affording sport, with the fisherman killing the birds for selling to taxidermists; two boatmen were bagging a hundred birds daily.[11]

Because it projects into the sea, Flamborough Head attracts many migrant birds in autumn, and is a key point for observing passing seabirds. When the wind is in the east, many birders watch for seabirds from below the lighthouse, or later in the autumn comb the hedges and valleys for landbird migrants. Flamborough Head has a bird observatory.

Danes Dyke is a 2-mile (3.2 km) long ditch that runs north to south isolating the seaward 5 square miles (13 km²) of the headland. The dyke and the steep cliffs make the enclosed territory and its two boat launching beaches, North and South Landings, easily defended. Despite its name, the dyke is prehistoric in origin, and Bronze Age arrowheads were found when it was excavated by Pitt-Rivers in 1879. It is a Local Nature Reserve.[12][13]

On the north side of Flamborough Head lies Thornwick Bay, a bay with a rock beach surrounded by cliffs.[14] The second part of the name Thornwick comes from the Old Norse word vík ('bay') (meaning that the modern name Thornwick Bay is tautologous). At the north side of the bay lies Thornwick Nebb, the final part of which comes from Old Norse neb ('promontory').[15][16]

A plaque at Thornwick Bay commemorates the 1952 loss of Robert Redhead, the bowman of the Bridlington lifeboat, while attempting to rescue two girls, Joan Ellis and Gillian Fox, from drowning.[17]
