Clacieres; Ice Cave; Preserve
The Ice Cave at Decorah, Iowa, is the largest known glaciere in North America east of the Black Hills and the subject of much international speculation during the latter half of the nineteenth century. A satisfactory theory for the formation of ice in late spring in this and other caverns was first proposed by Alois Kovarik after a series of meteorological measurements. Recent observations confirm his hypothesis. Because of its historical and geological interest and because it is the habitat of insects found nowhere else in North America, it has recently been included in the Iowa State Preserves System.
