Hello. I am trying to find out about a huge pyramid somewhere is
South America. I think it was on the discovery channel but I could
not locate any info about it from their site. This pyramid is has a
4-sided square base with base lengths 1/2 mile long. It is covered
with plant growth and until recently, they thought it was a
mountain. Has anyone heard of this? I would very much like a URL
link on it. Thank you.
