Background story

Phong Nha-Ke Bang National Park, Vietnam

Stalagmites, stretching for over half a kilometer, in Hang Son Doong. Hang Son Doong, in Phong Nha-Ke Bang National Park in Vietnam, is believed by many to be the largest cave on earth. It is more than four kilometers long, with a continuous passage as wide as 90 meters, and, in places, well over 180 meters high—spacious enough to accommodate an entire New York City block of 40-story buildings. It is part of a system of 150 or so caves, many still not surveyed, under the Annamite Mountains, formed two to five million years ago, when river water scoured a tunnel along a fault in the limestone.
