The St Lawrence River forms a complex international boundary on this early 20th-century survey, dominated by the turbulent Long Sault Rapids and a series of large islands like Barnhart Island and Sheek Island. On the New York shore, the industrial and transport hub of Massena is already well-established, positioned where the Grass River and Raquette River approach the larger waterway. The presence of the Cornwall Canal on the Canadian side and the emerging rail network of the Grand Trunk RR highlights the region's importance as a gateway for river commerce and power.
