A stack or sea stack is a rock formation made up of a steep or upright column or columns of rock in the sea near a coast. They are formed when part of a headland is eroded by water crashing against the rock or as a result of wind erosion. These impressive formations are intricately created by nature only through time, tide and wind. Here are 10 famous sea stack formations from around the World.
01. Dun Briste, Ireland
Dun Briste, a spectacular sea-stack, estimated to be approximately 50 metres (165ft) in height, stands 80 metres (260ft) off Downpatrick Head, in the town-land of Knockaun, east of Ballycastle, Ireland. Downpatrick Head is where the Atlantic has gouged a huge bay from the mighty cliffs and their summits scoured of all vegetation except grass by the ceaseless ocean winds.
Each year, Downpatrick is frequented by birdwatchers, who come to observe and record the many different species which take up positions on the stratified face of the stack as the seasons change. In May and early June, the headland itself is a blaze of colour when the sea-pink comes into bloom. Link Map
