If you happen to be fascinated by exploring underground chambers and tunnels or have an affinity for caves, you're in for a treat with this video. It takes us along on an expedition with a team of cave explorers, who travel to Papua New Guinea to search for underground rivers and new cave systems. What they find is simply amazing, while also discovering quite an adventure along the way. This clip is a few years old, but well worth watching if you haven't seen it before. It will help you understand the passion for exploration that many cavers have.
Thanks to my friends at Explorers Web for sharing.
