The Arab Mountain Fire Observation Station is a historic fire observation station located on Mount Arab at Piercefield in St. Lawrence County, New York. The station includes a 40-foot-tall (12 m), steel frame lookout tower erected in 1918, an observers cabin built about 1948, a trace of the foundation of the original cabin, a structure probably used as a root cellar in the 1940s, and the foot trail. 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.
