From your link: "They said they are going to build what the elders called the house in the sky."
Have you read Graham Hancock's book "Fingerprints of the Gods"? In the last chapter he is talking with an elderly indian man (I believe he was Hopi, but could have been Navajo...don't have the book here with me). And this man explained some of the "end time" prophecies of his people. Many of them are listed in your link. One of the last ones is when man builds a "house in the sky"...
of course, the International Space Station is well on it's way.
