Here it is 'uncensored' but not unexpurgated. I haven't read it all myself, but my understanding is that the geological record doesn't reflect a pole flip if it flips back again.

Depending on the rate of flip, there might be record in whatever lava is cooling provided you could find where it was flowing during the flip. From what I understand the flips take some time to accomplish, but since there were few devices to measure the changeback then I dunno. Haven't seen a decent explanation of what compasses indicate during this flip either. I believe they discovered this looking at stretch marks the plates make moving about
