The Geograph project started in 2005 with the aim of publishing, organising and preserving representative images for every square kilometre of Great Britain, Ireland and the Isle of Man.

The green colour of the water in the pit is due to very fine particles of clay suspended in the water. The same effect sometimes happens naturally in lakes fed by glaciers.
