Past cataclysms appear in print more than is recognized. Tales where the earth yaws wide and swallows cities or hapless humans who tumble into the yaw are not describing present day earthquakes which tumble buildings, drop bridges, and heave roads. Yaws that open and re-close may seem to occur only in story books, but they are based on real events that sometimes occur during cataclysms. Fairly tales sometimes describe mountains that rise from the earth overnight, or caverns and passageways into the mountains that open suddenly or disappear just as suddenly. This is all attributed to magic but to primitive humans who had no forewarning of a pole shift, emerging the morning after horrendous wind and rain storms to find the landscape rearranged must have seemed like magic.
