Deep Underground Military Bases (aka D.U.M.B.s)

In conspiracy theory, Deep Underground Military Bases (or D.U.M.B.s) are exactly what their name implies: secret underground bases built by the US military (via private military contractors) at exceptionally deep strata.

In past human history, we find accounts of ancient tunnels in Arizona built by the fabled “Ant People” of Hopi lore. We also read about the famous Nazi bunker of Adolf Hitler's final days —an exceptionally engineered bunker with bedrooms, offices, dining facilities, and environmental controls. It is speculated that Nazi scientists from Operation Paperclip were crucial for the success in engineering the first American D.U.M.B.s in the 1950s and 1960s, including the Cheyenne Mountain Complex (now part of the US Space Force).

According to witnesses, D.U.M.B.s exist all over the United States, with the heaviest concentration beneath the High Desert of the American West where the rock strata is strong enough to support the structures, and the lack of groundwater affords the least interference from flooding during construction, expansion, and ongoing operations.

Privately contracted long haul truckers claim underground highways connect these bases, stretching through tunnels for many hundreds of miles, complete with intersections, traffic lights, and gas stations.

FEMA's "Continuity of Government" initiative is rumored to include D.U.M.B.s in its plans to preserve key governmental personnel in the event of a catastrophic national emergency, such as nuclear war.
The US military has secretly built hundreds of Deep Underground Military Bases (aka D.U.M.B.s) all across the USA, especially in the American West, and Antarctica is said to have one of the largest singular, self-contained D.U.M.B.s in the world.

Hicks Underground Library is a place at Purdue University. From the outside it looks small but is actually quite large inside, much like the TARDIS from the show Doctor Who. Its is a popular place for students to go and study with friends.
Student 1: Have you ever been to Hicks Underground Library?

Student 2: What do you mean, 'have I been there'? I practically live in that place!
