DEEP UNDERGROUND, IN A FACILITY IN WESTERN PENNSYLVANIA, SOME OF THE WORLD’S MOST ICONIC PHOTOGRAPHS ARE STORED AT SUB-ZERO TEMPERATURES.
It isn’t even on a map. It doesn’t really have a name. Iron Mountain, the company that owns and operates the catacombs of this former limestone mine, calls the place “The Underground” – quotation marks included, as if to signify that it is as much an idea as a real, physical space. The old mine is by far the storage company’s largest and most secure facility – a level four, it’s called. Only a handful of government buildings (the Pentagon, the White House) have a security level that’s higher, five, which is as high as it gets, security-wise.
