Jewel Cave National Monument
( Originally Published Early 1900's )
Northwest of Wind Cave, thirteen miles west and south of Custer, South Dakota boasts another lime-stone cavern of peculiar beauty, through whose en-trance also the wind plays pranks. It is called jewel Cave because many of its crystals are tinted in various colors, often very brilliantly. Under torchlight the effect is remarkable.
Connecting chambers have been explored for more than three miles, and there is much of it yet unknown.
