1907 Map of Massena

About this map

The St Lawrence River and its complex network of rapids and islands dominate this northern border landscape before the mid-century seaway projects permanently altered the waterway. The map details a hydro-industrial corridor where the Massena Power Canal diverts water toward the growing industrial center of Massena. Along the river, substantial landmasses like Barnhart Island and Sheek Island are separated by the turbulent Long Sault Rapids and South Sault Rapids, features that once defined the character of the international boundary between New York and Ontario.
