Discovered by accident in one of the largest zinc and silver mines in northern Mexico, the Naica cave, filled with enormous selenite gypsum crystals, contains a highly toxic atmosphere. After years of preparation, a team of speleologists, biologists, and NASA members are exploring this natural wonder.
