We once thought that severe Sun spots could be the cause, because they do disrupt the Earth's inner electrical and magnetic structure, but we were wrong.

The time wasted on that assumption was the price for dealing in assumptions rather than facts. It was a bad detour to take. What was necessary was to be patient, to take more time; to assemble more facts; and use our most valuable tool, analytical reasoning. The solution, whatever it might be, would come.

The derivation of the process gave us a greater understanding of prehistoric events. For instance, you can see that ice ages are not a matter of advancing and retreating ice; it's simply that different areas of the Earth are in polar regions at different times, for different durations of time; changes between positions take place in a fraction of a day, and the accompanying | supersonic deluges deposit the various huge stratas we find in the walls of the Grand Canyon, Painted Desert, Monument Valley, the mountains around Mexican Hat, Canyon de Chelly, and the Moqui Dugway.
