This view is within or near to the spawning ground for North America's cyclical continental glaciations. At the top …is Hudson Bay (north is right), and the curvy Belcher Islands are actually sea bottom which has risen up due to the un-weighting of the ice mass. The circular shore is straddled by prominent moraines, from the last pulses of outward push in the final melt sequence. Countless lakes on the ancient surface of the Canadian Shield include the double bulls-eye Lac à l’Eau Claire, which is a twinned meteor crater. The sea in the lower right is close to the southern end of Baffin Island.
