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.
Grass was in failing health in 1952 when a group of five businessmen from

Geology
Alabaster Caverns State Park is underlain by Permian age sedimentary rocks (~300 to 250 million years old). The main cavern extends into the formation, is about wide and high. The cavern branches into boulder formations and smaller caves. A small perennial stream now flows through the cavern, fed by various lateral tunnels and seepage from the roof. In the geologic past, the river was once capable of completely filling the cavern, as the cave walls and gypsum formations show evidence of sculpting by rapidly flowing water. The air temperature ranges from 52˚F to 58˚ year round in the cavern.
