Subterranean waterfall







Ruby Falls is an underground waterfall within a cave in Tennessee, USA


A subterranean waterfall or underground waterfall is a waterfall located underground, usually in a cave or mine.[1] They are a common feature in cave systems where there are vertical or near vertical geological structures for the weathering process to exploit, and sufficient gradient between the sink and the rising.[2][3] The highest known subterranean waterfall is in Vrtoglavica Cave in Slovenia, and is at least 400 metres (1,300 ft).[4] A renowned example in the United States is Ruby Falls, 44 metres (144 ft) high, in Lookout Mountain Caverns, a show cave in Tennessee.[5]
