Hi Title Magicians, this is beyond fascinating. The true ancient history of our country is, once again, being covered up. Bigtime. What if we had grown up knowing the real antediluvian and ancient history of the American continent? Our perspectives would be radically changed on so many levels... meanwhile, take a look at this.
Oh, and btw, I did include an action, Grand Canyon tunnel scene in my shapeshifter erotic romance romance, HER MIDNIGHT STARDUST COWBOYS. That was before I'd learned this info. However, there are all those ancient-artifact caves, Egyptian and Chinese, that were discovered, that the Smithonian has covered up, and are now patrolled to keep everyone out.
