250-acre (1.0 km²) Spitfire Lake is a part of the St. Regis River in the Adirondacks in northern New York State. Along with Upper and Lower St. Regis Lake, it became famous in the late 19th century as a summer playground of America's power elite, drawn to the area by its scenic beauty and by the rustic charms of Paul Smith's Hotel. It is the site of many grand old summer "cottages" and Great Camps; Frederick W. Vanderbilt, Anson Phelps Stokes and Whitelaw Reid were among the summer residents.
