Kartchner Caverns: Alive With Wonder

Season 10, Episode 6 of 10

Imagine climbing in a sink hole on a remote Arizona ranch and discovering a fascinating - even mystical - underground environment. Explore the beauty and natural wonder of a "living cave," through the eyes of both the discoverers and visitors. From a mineralogical perspective, Kartchner Caverns is one of the top ten caves in the world. It has more richness and diversity of formations with names such as "soda straws," "butterscotch," "bacon" and "fried eggs." Kept secret for 14 years in order to protect it from cave hunters, learn how this marvel of natural architecture was formed (and is still forming), and examine the extensive construction and ongoing preservation efforts necessary to protect this fragile underground ecosystem.
