series: Cave People Of The Himalaya
air date: 2/28/13 4:00 AM
An archaeologist dangles from a rope spanning a cliff 800-feet tall. A dark cave opening looms 700-feet down and the only way inside is to rappel down from above. Dr. Mark Aldenerfer, self-proclaimed landlubber, is not happy performing aerial acrobatics, but he's doing it for science, while seven-time Everest climber, Pete Athans, belays him. They're on a mission, set within the world's highest mountains, to find ancient mummies and uncover secrets that have been hidden in these cliff-top graves for thousands of years.
