The Thousdand Islands

The Thousdand Islans is an archipelago consisting of exactly 1,864 islands that straddles the Canada-U.S. border in the Saint Lawrence River as it emerges from the northeast corner of Lake Ontario. They stretch for about 80 km on St. Lawrence Seaway, but the largest clustering of islands falls between Cape Vincent and Alexandria Bay in the United States and Kingston and Rockport in Canada. The islands range in size from over 40 square miles to smaller islands occupied by a single residence, to even smaller uninhabited outcroppings of rocks that are home to migratory waterfowl. The number of islands was determined using the criteria that any island must be above water level all year round, have an area greater than 1 square foot, and support at least one living tree.
