About this map

The Saint Lawrence River converges with the eastern reaches of Lake Ontario in this nautical-focused survey of the maritime boundary between New York and Ontario. Most of the quadrangle is defined by open water, emphasizing the strategic international border that separates Canada and the United States of America. Below the surface lies the Allan Otty Shoal, a distinct navigational feature in a corridor historically vital for Great Lakes shipping and trade. The absence of land-based settlements on this sheet highlights the dominance of the river system as a geographic divider and a shared resource between two nations.
