Dun Briste and the surrounding cliffs were formed around 350 million years ago (during the 'Lower Carboniferous Period'), when sea temperatures were much higher and the coastline at a greater distance away. There are many legends describing how the Sea Stack was formed but it is widely accepted that an arch leading to the rock collapsed during very rough sea conditions in 1393. This is remarkably recent in geological terms.

A large piece of rock at the top right of the image (approximately 4 meters square) has broken away. Amazingly, this event was witnessed and the resulting splash photographed by Olivier Lerebourg which can be viewed here. |

As the stack is safe from any land based predators, it is a safe haven for a vast array of bird species at nesting time. Occupied by Common and Greater Black Backed Gulls, Kittiwakes, Cormorants and Puffins.
