Excalibur Pot Cave in the North York Moors

Excalibur Pot is a natural cave in the North York Moors area of England. It is the only major cave known in the North York Moors, and is formed within the Corallian limestone of the Upper Jurassic. The entrance is in the normally dry stream bed of Hutton Beck, midway between Hutton-le-Hole and Keldholme.

Two short pitches of 8 m and 5 m descend to a large chamber, which is followed by an extensive inlet series, and a large main streamway accessed by a 4 m pitch. Several areas have admirable formations, far more elaborate than anything else found on the North York Moors. The sources of the water are various sinks in Hutton Beck, and the stream eventually resurges from Bogg Hall Rising in the adjacent Douthwaite Dale at Keldholme.
