April 5, 2012 World's Largest Cave

[SIZE="2"]Here is the mouth to the world's largest single cave passage found to date. It is the Son Doong cave in the dense jungles of Vietnam's Phong Nha-Ke Bang National Park.[/SIZE]



[SIZE="2"]The cave measures at least 262-by-262 feet (80-by-80 meters) in most places and is at least 2.8 miles (4.5 kilometers) long.[/SIZE]



[SIZE="2"]These are giant formations within the cave. Some of the giant stalagmites are more than 230 feet (70 meters) high.[/SIZE]

Didn't we have pics of this cave a few months back? I could be wrong. I often am.

It was smaller before they built the Hanoi Highway.

This one? http://cellar.org/iotd.php?threadid=26847

You even commented on it. BTW - I have no illusions about Tolkien's imagination. They probably dug out the cave after reading his books.

I thought that cave was this cave. But IIRC, this one ain't really a cave, more like two mountains fell against each other. Venezuela, I think.

Please note the helicopters.

Yes, that's the one I was thinking of. :)
