Hi Arrow. Thank you for posting about this subject. It is one of my favorite mysteries to read about. There is so much written about it that it takes a lot of time to study, but I love it.
I have been researching the connections between the Hopi and Tibetans for some time. There is so much information there to learn. In The Book of Hopi, it is mentioned that the Dalai Lama may be the "lost white brother" of the Hopi, and may have one of the Sacred Tablets of the Hopi. The beliefs of the Hopi and Tibetans are indeed very similar.
I have also been researching the "lost city of the Grand Canyon" that G.E. Kincaid discovered in 1909. Fantastic information there! There is still research going on as to the accuracy of Kincaid's findings. The entrance to the lost city is nearly inaccessible and to get equipment, cameras, etc. up to the cave entrance and set up inside the many tunnels will be a phenomenal task. I hope someone will be able to do that some day.
The Hopi peoples believe their Sacred Sipapu, the place from whence they emerged from the Third World, is in the Grand Canyon. Some believe that this is also where the Anasazi went back to when they disappeared.
Maybe some day I will write some articles on all this. It is all very interesting.
Here are just a few links to research at:
