2019 Map of Thousand Island Park

About this map

The Saint Lawrence River serves as a sprawling aquatic landscape where the international boundary separates New York from Ontario. This map centers on the dense archipelago of the Thousand Islands, characterized by major landforms such as Grindstone Island and Wellesley Island State Park. The settlement of Thousand Island Park is a prominent focal point on the southern shore of Wellesley Island, appearing alongside smaller communities like Fineview and Grandview Park. The geography is defined by a complex network of bays and channels, including the American Narrows and the Lake of the Isles. Numerous smaller island clusters like the Robinson Group and Eagle Wing Group illustrate the intricate maritime environment. Grounded in 2019 data, the map details a mix of established island residences and protected natural areas like Whitehouse Marsh.
