No, this is not Egypt it is North Dakota! And yes that is a pyramid, but it is not what you think.
The Safeguard Program was developed in the 1960s to shoot down incoming Russian intercontinental ballistic missiles. Built at a cost of 6 billion dollars in Nekoma, North Dakota, the site was a massive complex of missile silos, a giant pyramid-shaped radar system, and dozens of launching silos for surface-to-air missiles tipped with thermonuclear warheads.
However due to both its expense, and concern over its effectiveness and the danger of detonating defensive nuclear warheads over friendly territory, the program was shut down before it was even operational. Today its a military-industrial shell in the middle of nowhere, or in the words of Kaluz who added this great site to the Atlas, “a monument to man’s fear and ignorance.” [Boing Boing]
