Death has his gnarled hand on the shoulders of the cavers exploring the water-filled caves of Mexico’s Yucatan peninsula. If their equipment fails they will have made their very last dive, because it is often as much as half an hour or even an hour to the next air pocket.
In return, fabulous experiences await the intrepid explorer:
Nature’s own inconceivably wondrous cathedrals are inhabited by species hitherto unknown. The fantastic caves attract cavers with their own personal dreams of revealing the secrets hidden there.
Biologists, geologists and zoologists make the pilgrimage to Yucatan, Mexico, in search of the perfect altar for their ritual of derring-do and quest for beauty.
