Why Leave Home After 5,000 Years?

The American Southwest is a land of great mystery. One of the most baffling riddles is why the ancient native tribes of the Four Corners, having occupied the region for more than 5,000 years, abandoned their homeland in the 14th century. David Roberts, an award-winning author, veteran mountain climber, and scholar of the American Southwest, will discuss the latest archaeological evidence and what we know about why these people disappeared. His latest book is The Lost World of the Old Ones: Discoveries in the Ancient Southwest.
