Located in the Blue Ridge Mountains, access to the operations center is available via State Route 601 (also called Blueridge Mountain Road) in Bluemont, Virginia. The facility is located near Berryville, 77 km from Washington, DC.
The site was originally opened as a weather station in the late 1800s. It was used as a Civilian Public Service facility (Camp # 114) during World War II. At that time there were just two permanent buildings on the site: the administration / dormitory building, and the laboratory. Those buildings still stand, supplemented by many more modern buildings.
The underground facility within Mount Weather, designated “Area B”, was completed in 1959. FEMA established training facilities on the mountain’s surface (“Area A”) in 1979.
