Inside the Iron Mountain Vault Housing the ‘Lunch Atop a Skyscraper’ Negative

The Pittsburgh CBS affiliate went 220 feet below the pastoral landscape of Butler, Pennsylvania, to visit Iron Mountain‘s 1.8 million-square-foot land mine of a vault. It preserves many of the nation’s most valuable analog artifacts and houses a staggering amount of server space. There are several hundred thousand original prints of Hollywood movies, as well as the 11 million-image Bettmann Archive owned by Corbis, featuring the cracked glass plate negative of the 1932 ‘Lunch Atop a Skyscraper,’ among other iconic photographs. In the video above, see the impressive length to which the organization goes in keeping the facilities secure, digitally archived, and climate-controlled, which includes managing an underground lake.
