In the spring of 2009, Sims was a member of the first expedition to enter Hang Son Doong, or “mountain river cave,” in a remote part of central Vietnam. Hidden in rugged Phong Nha-Ke Bang National Park near the border with Laos, the cave is part of a network of 150 or so caves, many still not surveyed, in the Annamite Mountains. During the first expedition, the team explored two and a half miles of Hang Son Doong before a 200-foot wall of muddy calcite stopped them. They named it the Great Wall of Vietnam. Above it they could make out an open space and traces of light, but they had no idea what lay on the other side. A year later, they have returned—seven hard-core British cavers, a few scientists, and a crew of porters—to climb the wall, if they can, measure the passage, and push on, if possible, all the way to the end of the cave.

There’s a jungle inside Vietnam’s mammoth cavern. A skyscraper could fit too. And the end is out of sight.

If you saw the NatGeo channel's show on the cave, you saw the end of the tunnel when they reached the top of the mud calcite wall, about 980 feet from the calcite. But that forest inside the cave is surreal. It was mesmerizing, and I rewatched that part four times.

Those folks were down there about two weeks, werent they?

Reminds me of the Genesis cave from Star Trek 2 😀

Are pictures of these big enough for desktop background anywhere?

This must have been the special I saw the other night.

The only thing beyond "the 200-foot wall of muddy calcite" is an outside exit.

Pretty anticlimactic but the cave is unbelieveable!
