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]
