	[[Image:CRYSTALLAKE.gif\|left\|thumb\|450px\|Crystal Lake Cave]]CRYSTAL LAKE CAVE. Discovered in 1868 by James Rice, a [[LEAD]] miner in search of ore-bearing stone, Rice's Cave was found to contain a fabulous collection of crystals including argonite, travetine, satin stalagmite, stalactite, and calcareous spar. (1) Originally access the cave ~~had to be~~ reached by riding in a bucket lowered by rope down a forty-five foot shaft~~. Ownership of the cave passed to Charles Linden who named it Linden's Cave~~.		[[Image:CRYSTALLAKE.gif\|left\|thumb\|450px\|Crystal Lake Cave]]CRYSTAL LAKE CAVE.

	In the 1930s,the site was developed as Crystal Lake Cave by Bernard Markus, a son-in-law of Linden. (2) Markus operated the mine as a tourist attraction from 1932 until his death in 1944. The ownership then passed to Herbert Knockel and his wife Evelyn, a granddaughter of Markus. In 1978 the ownership of the land passed to James and Doris Rubel.

	It was Rubel who ~~began the replacement of electric lines first installed in the caves in 1940. He~~ hired Dennis Flint of Dubuque to replace the high voltage lines. The new lights were virtually the same as used in automobiles~~. They~~ are operated by a series of substations that transform the voltage from 110 to 12. The less heat generated helps prevent the growth of algae. Flint's background as a theater lighting designer also came in handy when deciding where to place lights which were operated by motion detectors.
