Site 556-4 44 20' 34" N – 73 22' 12" W
This site, located in the town of Willsboro, 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. During construction, a fatal accident occurred on December 6, 1960, which took the lives of two steelworkers, Robert W. Carter and Charles E. Kartin. This site is now in private ownership, functioning as an artists’ studio, framing company, and gallery.
