Underground Bases
2 documented theories filed under this subject.
- Base 211: The Nazi Antarctic BaseBase 211 is an alleged secret German base said to have been built under the Antarctic ice in Queen Maud Land during World War II. The theory grew out of Germany's real 1938-39 expedition to the region it named Neuschwabenland, the surrender of U-boats U-530 and U-977 in Argentina months after the war ended, and the US Navy's 1946-47 Operation Highjump. A 2007 study in Polar Record examined the underlying records and concluded no base was built; the claims continue to circulate.
- The Dulce Base Underground FirefightAn alleged 1979 violent conflict between U.S. military forces (Delta Force) and extraterrestrial entities within a secret multi-level laboratory beneath Archuleta Mesa.
- The Eisenhower Secret Bunker in the CanyonA Cold War theory claiming that Dwight D. Eisenhower spent time in 1959 not merely at publicly acknowledged retreats such as Camp David, but in a deeper, hidden bunker site carved into remote mountain or canyon terrain and connected to Eisenhower-era continuity-of-government planning. The theory blends real presidential retreats, real emergency-relocation concepts, and the broader secrecy surrounding atomic-age survival infrastructure.
- The Continuity of Government (COG) TunnelsA Cold War theory claiming that the United States built not merely emergency shelters but an underground duplicate capital — a “Second Washington” — beneath or around Mount Weather and related continuity sites, complete with command rooms, communications systems, elite accommodations, transport links, and the capacity to govern after nuclear war. The theory grew from real continuity planning, secret relocation infrastructure, and the public’s fragmentary awareness of buried federal facilities.
