Himalayan Megaquake

In a remote corner of the Himalaya, in the forbidden Kingdom of Mustang, mysterious caves, perched high on cliff faces and carved by humans thousands of years ago, have lain just beyond reach — until recently. In April of 2007, a team of climbers and scientists climbed inside the long-hidden chambers for the first time in modern history.

On June 8, 1924, near the summit of the highest peak on earth, British climber George Leigh Mallory vanished into the clouds and instantly became a legendary figure. Did Mallory and his companion actually make it to the top of Everest?

National Geographic Television’s Cave People of the Himalaya features American archaeologist Dr. Mark Aldenderfer’s expedition to explore burial sites of the Upper Mustang region of Nepal. Human remains and artifacts found in these cave tombs provide new insights into the lives and practices of peoples who inhabited this area thousands of years ago. In the 1990s, a high Himalayan cave in Upper Mustang, Nepal was discovered to contain 42 ancient people, buried on wooden bunk beds. 20 years after they were discovered technology has changed, and now, rather than testing for DNA in the marrow of leg bones, scientists tend to search for DNA using teeth. Dr. Mark Aldenderfer uses carbon dating to determine that the burials spanned over 450 years. This indicates these people adapted well to the "high and dry" climate of Nepal's Upper Mustang region, and thrived there for a long time.
