The fact that south of this ridge the drift is rarely, if ever, found, proves the ridge to have been the southern limit of the enormous masses of ice. Here is where the great ice glaciers were stopped and were melted by the recurring summer's sun, and were forced to deposit their loads of Canadian soil and rocks.
Here, then, in the valley of the creek, are the remains of what the ice transported from British America. It may be stated in general that the high ridge extending across the county east and west, just south of the general course of Bean Blossom Creek, formed the wall against which the masses of ice from the north during the glacial era of the world's history, piled themselves, unable to move farther south except in small quantities, which escaped through gaps in the ridge. The natural features of Jackson Township are too unusual and important to be passed over with only a cursory notice.
