After being sealed for over 10,000 years, this cave was discovered in 1963 when a group of workers were digging to build a highway overpass. Daily tours are available and last just over an hour. The cave stays a comfortable 72 degrees Farenheit year-round, and features not only beautiful rock formations but also the remains of prehistoric mastodons, saber-tooth cats and other ice age animals. After your tour, enjoy the shaded picnic area with a playscape for children.
