About this map

The Saint Lawrence River serves as the central focal point of this map, defining the international boundary between New York and Ontario. The river's complex navigation and topography are documented through features such as Ogden Island and the Murphy Islands, alongside several hazardous shallows like Murphy Shoal, Clark Island Shoal, and the Goose Neck Islands Shoals. The presence of the Ogden Island Range Lights indicates the importance of maritime safety and commercial transit through these waters.

While much of the sheet captures the open water of the river, the southern shoreline reveals the mouth of Brandy Brook and the proximity of transportation corridors along the American side. The map illustrates the geographical relationship between these river islands and the mainland during the early twenty-first century, providing a clear view of the aquatic landscape before significant modern alterations.
