"The question that now should be asked What is the character of the contact between the Huron and Hamilton? While one did not see it today yet I rather suspect the contact is an abrupt one and that a kind interval may have intervened between these two formations or that the Huron change came in suddenly. The Sturgis Point Hamilton should be compared with Onwago to see if the latter has a larger time section. Comparison should also be made with Alpena. The fact that only a little Hamilton occurs in the Hudson Bay county is suggestive that elevation is going on in this middle-northern region changing the paleogeography and bringing in Haast beds from Michigan eastward to Onwago."
