Lake Huron defines the vast maritime boundary of this northern frontier, where the international border separates the Michigan mainland from the sprawling reaches of Manitoulin Island and Cockburn Island. The industrial pulse of the Michigan shore is centered on Alpena and Rogers City, with the Detroit and Mackinac RR skirting the coastline to serve the region's timber and limestone resources, evidenced by the large Quarry near Adams Point.
