Where did all the people who built this 'stuff' go?

I ask myself that same question every time I look at anything to do with pre-Columbian South America.

for example, the above image of Saxsayhuaman shows how massive the complex really is. That jigsaw outline in the above image is the wall we usually see depicted:

have you downloaded Google Earth yet? I can give you some links to truly stunning images. Massive earthern walls, hundreds of miles of canals...ancient terraces and ruins.

I saw a film years ago with an archaeologist in an airplane, poor grainy film, showing the Amazon plains. He went on and on about all the earthworks he was showing us below. They went on for hundreds of miles. He estimated that a population of 50 million would have been necessary to acomplish what he was showing.

BTW, he first caught a glimpse of that area from a commercial jet.
