The St. Clair River serves as the dominant corridor of this pre-war military reconnaissance, separating the bustling rail hubs of Port Huron and Sarnia. On the Michigan side, the landscape is defined by its industrial and administrative infrastructure, including the U.S. Customhouse and the Pere Marquette Ry. yards. To the south, a string of riverfront settlements and railroad stops like Marysville, South Park, and Recors indicate a region shaped by both maritime transit and overland trade.
