"The magnetic variation of the earth changes at a rate of 50.27secondsof
arc peryear." That seems a bit low to me. At that rate six degrees of
change would take 430 years.

Yeah, weird, eh? So I ran across this section of a site explaining
that it's often really a lot faster than that (2-25 years per degree).

The "Local magnetic anomalies" section mentions the Ramapo area by me.

The "Where were/are/will be the magnetic poles? " talks about the
movement.

And the section about the "reversing Earth" theory is just plain
terrifying :-) (Not just reversal of the poles... but the entire
crust rotating upside down in a matter of days... ouch!!)
