This site, located just outside of the town of Au Sable Forks, was an Atlas Missile silo from its construction in 1961 until its deactivation in 1965. It was one of 12 Atlas F silos constructed in a ring around Plattsburgh Air Force Base, at a cost of around $3 million each. This site is now in private ownership.
