Devil's Grinding Mill
Devil's Grinding Mill 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 located 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.
