George----I am NOT talking about the Magnetic North Pole which wanders every day----I am talking about the axis of rotation of the earth---the true north pole----it moves too! The first notice of it was in the late 1800's from the more accurate astrometry that became possible then.
The Magnetic North Pole has moved hundreds of miles since 1950---in fact over thousands of years the magetic poles will reverse----in the last million years the magnetic poles have swapped several times. It is this swapping that allowed the verification of continental drift in the late 1950's-early 1960's.
The movement of both the poles make the geological positioning history of land masses quite complicated.
