Mars was held below Saturn for a few thousand years at least. Mars lost 3 kms of it's northern surface when that occured. It took thousands of years but the connection points to that current are the Anode blisters we call Olympus Mons and it's kin.
The Earth was being held at the north pole. The Canadian Shield would have been solid where those Islands are now, and over the course of 5000 or so years they were hit by stupendous mega lightening, carving the islands and fjords we see today.
The idea that one pole is slightly bent in and another slightly pushed out (Arctic vs Antarctic masses) is common in Geodes as well, which we now know indicates the current path through the geode during it's creation.
