In 1974, a pair of young cavers discovered a narrow crack in a hillside of the Whetstone Mountains with warm, moist air flowing out of it. The cavers spent several hours crawling into a pristine cavern. They kept their discovering secret for another four years until they told the couple that owned the land. The existence of the caverns remained a secret for another decade until the state bought the land and designated it a state park. Almost immediately, Kartchner became one of the top ten limestone caves in the world. Still pristine, Kartchner is a wet or "live" cave, which means its calcite features are still growing. Two 1.5 hour-long tours are offered daily. Doing at least one is a must-do.
