Mount Laguna Air Force Station is located atop Mount Laguna, with a steep drop into the Anza Borrego desert. It was a DEW (defense early warning) site, watching for incoming missiles, and housed about 170 people until it was downsized in 1981. Now it is a multi-use satellite and radar communications site, operated primarily by the FAA, out of Los Angeles Center. Currently, about 6 people stationed there. A demolition crew from the Marine Corps has been practicing on some of the buildings.
