A new approach for dating archaeological sites is described. The method is inspired by Hapgood’s hypothesis that patterns of glaciation and ice ages can be explained by shifts in the geographic location of the North Pole. We have identified over fifty archaeological sites throughout the world that could have once been aligned to north (i.e., to one of these past poles) when the sites were first established but are now misaligned due to subsequent pole shifts. An algorithm is described that fuses the location and orientation of these sites with Hapgood’s original climate-dated pole locations to infer the date of construction of the associated sites. The results suggest that these sites may be far older than is currently thought.
