Port Huron Michigan sits at the southern tip of Lake Huron where the St Clair River begins — the Blue Water Bridge crossing to Sarnia, Ontario is one of the busiest US-Canada border crossings in the Midwest. Sarnia hosts Chemical Valley — one of the largest concentrations of petrochemical plants in North America — creating cross-border industrial accident risk. The St Clair River and Lake Huron create flooding and ice jam hazards. The city hosts the Edison Museum and significant maritime history.
