  1. buriedtoodeep Hey mate. The reversal of the poles are a geomagnetic reversal, not a geographical reversal. It just means that magnetic north and magnetic south switch. The last time this occurred was 780,000yrs ago. We can trace 183 reversals dating back 180 million years so far by studying Planet geology.
