The Thousand Islands run for about 50 miles along the Saint Lawrence River between New York and Canada. The chain includes almost 1,800 islands ranging in size from Wolfe Island at 40 square miles down to just a few square feet of rocks with one tree. (Rocks have to have at least one tree to be considered an official Thousand Islands island.)
In addition to the region’s popularity as a vacation destination, the famous salad dressing was named after the islands. Thousand Island dressing was developed by a local fishing guide’s wife. The dressing quickly became a regional favorite and became popular across the country after it was picked up by George Boldt for use in the Waldorf Astoria Hotel in New York City.
