The Mount Weather facility is a major relocation site for the highest level of civilian and military officials in case of national disaster, playing a major role in continuity of government. The facility itself is accessible through three surface entrances guarded by 25 ton blast doors that protect the mountain complex from chemical, nuclear and biological attacks. The facilities all clear protocol has since been engaged in the following years after the apocalypse, disengaging the magnetic locks on the blast doors leading into the mountain. Since the early days of the apocalypse, the mountain has stayed sealed until now. It is unknown if any personal cleared for the facility ever made it inside.
