St Lawrence River defines the international boundary in this mid-century hydrographic and topographic study, where the waters of Ontario New York meet the northern reaches of St. Lawrence County. The landscape is dominated by the sprawling Galop Island, which sits as a major geographic feature between the American and Canadian shores. Navigational markers including a Tower, several Light placements, and a Weir underscore the importance of the river's channel during this era of Seaway operations. On the mainland, the small settlement of Red Mills is situated near the riverbanks, served by the local Ross Road. This 1963 field check offers a precise view of the river's islands, including Benedict Island, during a period of significant maritime coordination between the Canada United States border.
