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.

A new addition to our above ground activities is the Labyrinth Tour.  This is a fun, physically challenging surface tour that explores picturesque rock outcroppings in the beautiful foothill forest surrounding the cavern.  This expedition involves hiking, climbing, crawling, sliding and slithering over, under and around mammoth rock sculptures that were created over 100 years ago when gold miners did hydraulic mining, washing away tons of soil exposing the massive rock structures.

Our 3,000 square foot Visitors Center provides information on Black Chasm Cavern’s connection to the Matrix trilogy, and displays 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”.
