"LITTLE COTTONWOOD CANYON - A few miles up the canyon there are 3 switch backs on the north side of the road, with security signs posted, leading up to the "granite" cliffs. The first switch back leads to the underground records vault maintained by the Mormon church, which has an underground but "off limits" connecting passage which leads deeper into the mountain, to a massive cavern where military and alien personnel collaborate, and in which witnesses have observed massive construction projects, and large underground buildings in which humans and greys have been seen working at benches on electronic [mind control, etc.] equipment.

Also, reports of a "Melchizedek" lodge penetrating the Mormon/LDS and Masonic lodges, the Mt. Shasta Mayan colony, and other 'lodges' in Sirius and Arcturus, which have formerly maintained treaties with the grey aliens although many of them have turned against the greys as a result of their betrayals of interactive treaties. The 2nd and 3rd switch backs going up the canyon both intersect at the same point, which is apparently the main surface entrance to the underground "military" facility.
