In this same general region lies another prominent Black Hills landmark which every tourist should take time to visit—Mount Coolidge. With a height of 6,400 feet, this peak is by no means an outstanding mountain, being ranked by a good half dozen higher within the Hills. But from its summit, which can be reached by an auto road leading off U.S. 85A a few miles to the north of Wind Cave Park, an amazing vista can be seen. To the east, on a clear day, the White River Badlands loom as a great valley sixty miles away. To the south one can see across the high rolling hills all the way into Nebraska, and to the west landmarks in Wyoming are clearly visible. On the summit a stone lookout tower has been built for the convenience of visitors. _Jewel Cave and Ice Cave_ Since the Black Hills are underbedded so widely by limestone, it is not surprising to find in them not one but several memorable caverns. There are, as a matter of fact, a dozen or more well-known large caves; but outside of Wind Cave, only Jewel Cave has been opened and fully prepared for public visit. The expense of exploring, lighting, and carving trails in the others has kept them off the market, so to speak, for in a region so packed with scenic delights two great caverns are about as much as the traffic will bear. Jewel Cave lies some fourteen miles west of Custer on U.S. 16, almost at the Wyoming-South Dakota border. It is a small cave, with only two tours marked out in it, one a mile long and the other two miles. It is noted for its wealth of colorful crystalline deposits, totally unlike the delicate filigree work to be found in Wind Cave. The cave was discovered by two prospectors, who proceeded to develop their property for commercial gain. In 1934 they sold the cave and such of its environs as they owned to the Newcastle, Wyoming, Lions Club and the Custer Chamber of Commerce. These two organizations sought to popularize it further as a lure to tourists who would have to travel through their towns to reach the scene. In 1938 the federal government took it over and made a national monument of it. Not far from Jewel Cave is the famous Ice Cave. This cavern gets its name from the current of cold air which blows from its mouth, cold and clammy on even the hottest of summer days. The Ice Cave is not officially open to the public, and has not even been totally explored. Forest rangers and Park Service employees have charted some of it and have searched out certain channels in the strange formation, and from their meager reports it would seem that if Ice Cave is ever fully opened it will vie with New Mexico’s Carlsbad in beauty and grandeur. For the curious tourist the only possibility at the moment is to take the lovely off-route trip to the cave’s entrance, a natural arch twenty feet high and seventy-five feet wide.
