The Doomsday-esque North Dakota Bunker
To be clear, this is not a doomsday bunker... it just looks like one. This bizarre trapezoid concrete building is apparently used to measure weather patterns and seismic waves. Sure, it really just looks like a doomsday bunker but we'll take the government's word for it. Rumors that have swirled in the nearby North Dakota counties say it was used as a national missile defense system at one point. That makes more sense!
