The History Channel had a program that highlighted Erik VonDaniken and it had a segment about Nazca that had a picture of this mountain. Though the picture is small (it's the best I could find--sorry), it is easy to see that it is a large mountain, and it would take a Herculean effort and then some with unusual skill to level off a mountain of that size. But that isn't the unusual part--the unusual part is that there is no debris from the mountain top. There is no debris in the valley, and they have found no debris anywhere within miles. What happened to the mountain?
