Ever wonder what it's like to work 220 feet underground? Want to find out?

You’d be hard pressed to name another place quite like the Iron Mountain Underground -- an ultra-high security facility 220 feet beneath the surface, that was once a limestone mine. That’s where a select group of Iron Mountain employees work every day, trusted with some of the world’s most vital assets.

If you've never been to The Underground, you likely have some questions about who works down there, what do they do, and what’s it like? We had the same questions -- so we asked a few people to share their personal stories.

Find out what we unearthed.
