Welcome to Coober Pedy's American cousin: Seattle. Yes, parts of Seattle's old downtown lie buried beneath modern-day streets. After the Great Seattle Fire of 1889, the city was rebuilt on top of the old ruins, which still exist today and can be toured via the Seattle Underground.
3. The Statue of Liberty Was Almost Placed in a Different State

During the height of the Cold War, the U.S. military considered a top-secret project known as "Project A119"—a plan to detonate a nuclear bomb on the moon. The idea was to demonstrate military superiority over the Soviet Union in a dramatic and visible way. Thankfully, it never happened.
8. There’s a Town That Renamed Itself to Get Free Internet

12. Alaska Is the Westernmost, Easternmost, and Northernmost State

13. There’s an Island in New York That’s Forbidden to the Public

14. The U.S. Has a Desert That Gets Snow

15. There's a Tiny Piece of the U.S. in Canada
