The water eventually evaporated, leaving behind huge deposits of alabaster and other minerals. Upheavals of the earth raised the gypsum bed close to the surface. Over time, water streams tunneled caverns through the formation, which contains an abundant quality of selenite crystals, white and pink gypsum as well as deposits of rare black alabaster. There is no official record of discovery for Alabaster Caverns, even though they were known to have been used as hideouts by outlaws in the 19th Century. The first documented exploration of the caves occurred in 1898, shortly after Hugh Litton homesteaded the area in 1893. Several individuals leased land around them during the 1920s and 30s, and allowed limited tours of the caverns, which they called "bat caves." In 1939, an Englishman named Charles Grass bought the land. began renovating the caves, and opened them for public tours. It was Grass who gave them their current name.
