St Marys River serves as the critical maritime artery in this mid-1980s survey, marking the international border between Michigan and Ontario. The Soo Locks stand as the focal point of commerce and navigation, enabling transit between the lower Great Lakes and the expansive waters of Lake Superior. The map details the transition from the industrial activity at Sault Ste Marie to the rural character of Sugar Island, where small settlements like Payment and Churchville Pt overlook Lake George.
