The Rockies are fifteen hundred kilometers, or one thousand
miles, to the east. The cause must be the tectonic plate that built these
mountains. Its name is Farallon. Farallon started off normally enough. It
plunged beneath the North American Plate at a forty-five degree angle. This
process sprouted volcanoes to form the Sierra Nevada in what is now California.
Next, mantle motions pulled North America westward over Farallon, and the plate
scraped along the bottom of the continent - for fifteen hundred kilometers. As
North America continued its westward trek, Farallon settled to the bottom of
the mantle.
