. The persons who made the discovery were cave guides Jack Kyker and Clarence Hicks, who were exploring in the cave during their off hours. They reported their find to Dr. W. J. Cameron and W. E. Michael of Sweetwater, who were the current owners of the cave. The owners submitted the bones to the American Museum of Natural History in New York City, where they were identified as bones of a very large jaguar and an elk fawn. George Gaylord Simpson, a vertebrate paleontologist at the museum, subsequently visited Craighead Caverns in May, 1940 where he recovered additional jaguar bones and made casts of several jaguar footprints in the mud floor of the cave. His excavation and findings are reported in American Museum Novitates, No. 1131 (August 6, 1941) on pages 1–12. The report includes photographs of the bones and footprints.
A mushroom farm was operated in the cave from 1939 to 1940. The manure for this operation was supplied from Fort Oglethorpe, where many horses were stabled. The mushroom beds were located in the Big Room, a few hundred feet northeast of the Historic Entrance. In 1947, a wooden dance floor was built in this same area of the cave, and a nightclub, known as the "Cavern Tavern", was operated in the cave.

The Lost Sea
The visible surface of the lake measures 800 feet long and 220 feet wide (4.5 acres) at normal "full" capacity. Cave divers have explored several rooms that are completely filled with water, without reaching the end of the cave. This exploration was conducted in the 1970s.
For many years The Lost Sea was considered the world's largest underground lake and is still recognized as the world's second largest underground lake.
Boat tours of the lake are still given and for many people are the highlight of the tour. In times of extreme drought (such as 2007-08) the lake recedes significantly and the management had to extend the walkway and the boat dock in order to be able to provide the boat tours. According to the management of the Lost Sea, the water level in the lake dropped 28 feet below its normal level at the height of the drought. At such times visitors see a much larger cavern above the lake surface.
