Cosmic Cavern was discovered in 1845, but wasn't developed until 1927. The cave features a 9 foot soda straw - the longest known in the Ozarks, and two bottomless lakes, one of which has had trout in it for over 50 years. One of the lakes was discovered in 1993 in the "Silent Splendor" section which made national news. This was Arkansas' most delicate discovery. The cavern is home to the extremely rare Ozark Blind Cave Salamanders.
