Boston Bay, looking north from Weymouth, Massachusetts
Drumlins, left when the great ice-sheet melted, are seen rising above the waters of the bay. In the Pleistocene epoch (the last geologic epoch before the present time) most of the northern and eastern North America was covered by a great glacier, similar to the one which now covers Greenland.
