Inside Arizona's Hidden Limestone Cavern That Remained Secret Years After Its Discovery By Two Students

Two college students crawled into a muddy crack in the Whetstone Mountains back in 1974 and found something so precious they refused to tell anyone for years. Warm air drifting up from a sinkhole led them to a giant underground world of glittering rock still growing today. For more than a decade, hardly a soul knew it existed. Now it sits near Benson, Arizona, waiting for curious folks who love a real hidden treasure. A Living Cave Waiting Beneath the Whetstone Mountains © Kartchner Caverns Stat
