We are thinking of clouds. This is another wave cloud. The photograph was taken in 1999 by Beverly Shannon and the cloud has formed over Mt. Shasta. Mt. Shasta is a volcano in the Cascade Ranges of North America
Mt. Shasta has become the focus of myths and legends, both native American and New Age.
One of the myths concerns this cloud formation. This is a Lenticular cloud taken at sunrise and reflected in Lake Siskiyou. The clouds are said to be the hiding places of UFO's because of their plate shape and formation.
Mt. Shasta's energy is said to be magnetic and healing. The town of Mt. Shasta has 16 Christian churches and a Buddhist monastery. Numerous cults and sects believe it to be on an energy grid.
Apart from the UFO's, there is the story of the ancient race of Lemurians from the drowned continent of Lemuria who live inside the mountain and can appear and disappear at will. These beings supposedly mastered atomic energy, esp, electronics, science and had airships which flew them to Atlantis. They don't seem to have mastered geology since they couldn't stop Lemuria disappearing under the sea.
In the meantime it makes some fantastic clouds and not a bad rainbow.
