Geological evidence indicates that a cosmic wavefront impacted our solar system around 12,900 years ago and triggered a POLE SHIFT. The land mammal extinction episode that occurred during this interval was the worst since the extinction of the dinosaurs. There is a finite chance that one such event could arrive within the next few decades. Linking his scientific findings to details preserved in the myths and monuments of ancient civilizations, Dr. Paul LaViolette demonstrates how past civilizations accurately recorded the causes of these cataclysmic events, knowledge of which may be crucial for the human race to survive the next catastrophic superwave cycle.
