Wind Cave Boxwork
Candles and a String
In 1881, Charlie Crary of Custer squeezed through the small Natural Entrance and became Wind Cave’s first known explorer. Using candles for light, and string to mark their route, he and friends scrambled on their hands and knees into the darkness. In their flickering candlelight, they were probably the first people to see a rare cave formation known as boxwork.
