The Mystery of the Sphinx presents the geological evidence that The Great Sphinx was weathered by water, not wind and sand. But there has been water in the Sahara for almost 9,000 years. That makes The Sphinx almost twice as old as history tells us.

The Expanded Version, at 93 minutes, contains all the information in the original Broadcast Version, and much more. Included are bonus interviews with experts, rare archival photos of The Sphinx, additional geological findings that support the Sphinx's ancient age.
