🌬️ Devil's Grinding Mill

The Devil's Grinding Mill, sometimes known as the Devil's Hole, is part of The Angel's Drainpipe, a partially collapsed cave system on the River Eden in England, which forms dramatic gorges and natural arches. It is south of Kirkby Stephen, within Stenkrith Park. The water moving with the caves and gorges produces an incessant roar. Geologically it is unusual as it has formed not in true limestone, but in brockram, a breccia of limestone fragments within sandstone.
