2023 Map of Barnhart Island

About this map

The Saint Lawrence River serves as the dominant geographical feature and international boundary on this modern topographical study of the New York borderlands. Centered on the intricate shoreline of Barnhart Island, the landscape is defined by the transition between the river's main channel and the northern reaches of New York. Recreational and access points such as Barnhart Island Beach and Massena Point are clearly delineated, connected by local routes including Barnhart Island Rd and Barnhart Isle. This survey illustrates the contemporary physical geography of the river system, documenting the land-to-water interface where the Canada United States of America border follows the deepest part of the waterway. The map provides a precise layout of the modern island infrastructure and hydrography within the St. Lawrence River valley.
