Alabaster Caverns State Park
Alabaster Caverns State Park is a state park approximately south of Freedom, Oklahoma, United States near Oklahoma State Highway 50. It is home to the largest natural gypsum cave in the world that is open to the public.〔Allen, LaRadius. (Alabaster Caverns State Park ), ''(Encyclopedia of Oklahoma History and Culture )'' (accessed May 19, 2013)〕 The gypsum is mostly in the form of alabaster. There are several types of alabaster found at the site, including pink, white, and the rare black alabaster. This black alabaster can be found in only three veins in the world, one each in Oklahoma, Italy and China. Another form of gypsum can be found in the many beautiful selenite crystal formations.〔(Alabaster Caverns State Park ), Oklahoma Tourism and Recreation Department (accessed May 19, 2013)〕
==History==
The first documented exploration of the caves occurred in 1898, shortly after Hugh Litton homesteaded the area in 1893.〔 Public tours of the caves began in the early 1900s and increased with the 1939 purchase and renovation of the caverns by Charles Grass, who gave them their current name.〔
The U.S. state of Oklahoma purchased the land from Grass on September 1, 1953, for $34,000, reclassifying the land as a state park in 1956.〔
