The underground portion, which few know about, was designed by folks from the Research & Development department of Walt Disney Imagineering, as well as the FBI and CIA, with many of the same features that are used in the Pentagon and the White House. Disney is still reaping the benefits of Walt's work for the FBI.

Moving eastward, from the CC, you quickly come to a huge cavern. This is directly under the Matterhorn Bobsleds attraction. In the event of a major catastrophe that threatens the mountain, the attraction will retract into this cavern and be protected from harm. In recent years, some of the mechanisms that make this possible have been experiencing slight problems, resulting in minor "sinking" on the part of the Matterhorn. Also, water from the Submarine Lagoon has been known to leak into this space, and cast members have been known to swim in the makeshift pool on hot Summer days. So, the next time someone tells you that the Matterhorn is sinking, or that the Submarine Lagoon is leaking, you'll know what they are talking about.
