Aquamole Pot

Aquamole Pot is a limestone cave in West Kingsdale, North Yorkshire, England. It was originally discovered by cave divers who negotiated 168 metres (551 ft) of sump passage from Rowten Pot in 1974, to enter a high aven above the river passage. All subsequent major explorations were undertaken from below before an entrance was opened up from the surface. It is part of a 27-kilometre (17 mi) long cave system that drains both flanks of Kingsdale.
