Tiahuanaco Geoglyphs Coast to Coast AM (George Noory)

David Flynn talks about the Geo-glyphs (like the Nazca Lines) and Megalithic structures at Tiahuanaco in Boliva on Coast to Coast AM with George Noory. Tiahuanaco is the site of astonishing megalithic structures. This interview took place on Feb 29, 2008. From Coast to Coast AM:

First hour guest, author David Flynn, discussed evidence for ancient geoglyphs centered around Lake Titicaca in Bolivia. According to Flynn, the massive patterns cover an area of 20,000 square miles and appear more like abstract art than other geoglyphs, like the Nazca Lines. Flynn believes the geoglyphs could have been built by giants. View photos and read more about his discovery at officialdisclosure.com.

This site is estimated at over 17,000 years old. That alone makes Tiahuanaco a complete mystery.  Men were not supposed to have the tools or skills required to build this and the video below shows more evidence of why it is so perplexing. I highly recommend this clip from the History Channel - Ancient Aliens about Tiahuanaco and Puma Punku.
