I wonder how many of you have heard of this lesser-known Archaeological conspiracy.
Apparently some Ancient Egyptian ruins were found inside the Grand Canyon. In 1909, a small-time newspaper known as the
Arizona Gazette published an article on it.
Some people have claimed to come across an "odd rock" off of a smaller hiking trail (not sure which one exactly, as no one really knows). It appeared to them that it was "welded shut", and the National Park security team claimed that area off-limits.
I wonder just what they would be hiding there. Here's some articles that further investigate the matter:
