 Have you heard of the U.S. Atomic Energy Detection System? The system operated by the U.S. Air Force helps keep tabs on nuclear detonations around the globe. In the early days, part of the system was operated outside of Encampment, Wyoming. In 1955, the Air Force deployed a team to set up monitoring equipment west of Encampment. The station was part of a network of sites throughout the U.S. and allied countries to help detect nuclear detonations. At Encampment, seismic monitoring was used to detect waves moving through the Earth from nuclear blasts. Since the equipment was located about 10 miles away and connected via cables to the station in town, personnel spent a lot of time maintaining equipment against severe weather, including snowstorms and lightning strikes. The Encampment unit ceased operations in 1972. Wyoming hosted additional seismic monitoring sites near Glen Rock and Boulder. While the name has changed over the years, the Atomic Energy Detection System continues its monitoring mission. In fact, the station in Boulder continues operating today.
