The St. Regis Mountain Fire Observation Station is a historic fire observation station located on Saint Regis Mountain at Santa Clara in Franklin County, New York. The station and contributing resources include a 35-foot-tall (11 m), steel frame lookout tower erected in 1918, the site of the former observer's cabin, and 9/10 of a mile foot trail between the cabin site and summit. The tower is a prefabricated structure built by the Aermotor Corporation and provided a front line of defense in preserving the Adirondack Forest Preserve from the hazards of forest fires.
