There are a great many underground and underwater tunnels and facilities. They can be impressively large and deep. Depths can easily
range to one vertical mile underground, which is comparative child’s play for the technology in the Black Budget world, and even deeper.

People have no idea what kind of deep labyrinth is beneath Camp David and under the surrounding region. I have informally been told that some bases are miles deep.
