Hull Pot

Hull Pot is a collapsed cavern measuring 91 metres (300 feet) long by 18 metres (60 feet) wide by and metres (60 feet) deep. During dry weather, the beck goes underground further upstream before it re-emerges as a waterfall in the pot itself. Hull Pot beck is normally dry, but after heavy prolonged rain the beck flows into Hull Pot resulting in a spectacular waterfall and occasionally completely filling this enormous hole in the ground.
