A group of some 81 large boulders resting in a sea worn gully. Consisting mainly of diorite, and porphyritic granite these stones originate from Jersey's south coast but now rest on top of the native Rozel conglomerate. It is unknown how they got there. Burdo examined them in 1928 and suggested that they may be the remains of a prehistoric monument that came to rest on the bedrock as the land below them was eroded away by wave action.
