Niagara Cave is a limestone cave located in Harmony, Minnesota. The cave is approximately 200 feet (61 m) deep; features include an underground stream, 60-foot waterfall, fossils, stalactites and stalagmites.[5] The cave is privately owned, with tours available seasonally.[6]
The cave was first discovered in 1924,[2] and in 1932, three spelunkers Al Cremer, Leo Tekippe, and Joe Flynn explored the cave and named the site Niagara Cave.[7] Niagara Cave opened as a show cave in June 1934,[4] and was described by geologist J Harlen Bretz in 1938.[8]
The Minnesota Geological Survey noted in their 1995 survey, "Niagara Cave contains an excellent example of an underground river, complete with waterfall."[9]
