Hull Pot is a great big hole in the ground, 300 feet long, 60 feet wide, and 60 feet deep. It’s actually a collapsed cavern and, according to my very quick research, it’s the largest natural hole in England. The hole lies on the watercourse of Hull Pot Beck. During dry weather, the beck goes underground sometime before the hole, and re-emerges as a waterfall in the pot itself. The stream bed that leads to the rim of Hull Pot is normally dried up, but in wet weather when the water table is higher, the stream runs over the top as well as underground – resulting in a spectacular waterfall crashing down into the bottom of the pot. The water then disappears again on it’s subterranean journey, making a brief appearance at Tarn Bar before finally re-emerging at Brants Gill Head.
