Beautiful formations in Black Chasm Cavern.

Black Chasm Cavern was designated a National Natural Landmark by the National Park Service in 1976 after being recommended by local members of the National Speleological Society, and as such is considered a “nationally significant natural area.”  Visitors to the cave are enchanted by the beauty of a wide variety of formations including stalactites, stalagmites, flow-stones and the vast arrays of rare helictite crystals, for which Black Chasm Cavern is justly famous.

Our 3,000 square foot Visitors Center provides information on Black Chasm Cavern’s connection to the Matrix trilogy, and display props from the movies: huge manufactured stalagmites from the Zion set. In addition, information is displayed on the discovery and mapping of numerous fragile, highly decorated, small chambers in Black Chasm Cavern by a team headed by Dr Hazel Barton who starred in the iMax movie “Journey into Amazing Caves”.
