Wandering the north magnetic pole through geologic time. although students of ancient rock magnetism regard this path as fairly well established, there is no conclusive proof that the geographic pole followed the same path or that the continents maintained their same positions during this lengthy period. Notice also that there are no signs of frigid conditions or glacial action in northeastern Asia during the periods when the pole was supposed to be in that vicinity. Stokes, 1960, p. 168.
