The Great Stalacpipe Organ
Located deep in the Luray Caverns in Virginia's Shenandoah Valley is the Great Stalacpipe Organ, the worlds largest musical instrument.
Stalactites covering 3 1/2 acres of the surrounding caverns produce tones of symphonic quality when electronically tapped by rubber-tipped mallets.
This most unique, one-of-a-kind instrument was invented in 1954 by Mr. LeIand W. Sprinkle of Springfield, Virginia, a mathematician and electronic scientist at the Pentagon
