Arizona Tries to Save “Living Cave”

In 1974 cool, moist air billowed from a crack in Arizona’s sunbaked desert and lured cave hunters Randy Tufts and Gary Tenen underground. There, glistening formations of rock hung from the ceiling like icicles and sprouted from the ground. The explorers were overwhelmed. They’d discovered a so-called living cave.

Tufts and Tenen were the first humans known to set foot in the Kartchner Caverns, which today are among the world’s top show caves.
