US Gypsum Plant, Shoals, Indiana, 1978

Today I discovered a wonderful slide show of the US Gypsum mine and board plant in Shoals, Indiana. The photos date from 1978 — check out that Farrah Fawcett poster in the mine lounge! If you look at the photos individually, there are notes explaining the context.

I was still attending Shoals High School in 1978. Every year USG graciously hosted the local eighth grade class for a tour of the board plant, introducing them to the town’s largest industry.

New use for old gypsum mine

What can you do with a hole in the ground? From a 2001 story in USAToday:

Image from

Underground Secure Data Center Operations (USDCO) opened 4 months ago in an abandoned gypsum mine in Michigan. From 85 feet underground, the company plays host to the computer systems of 22 clients. Client headquarters are as far as Australia, but their mission-critical systems are operating from the mine beneath Grand Rapids and over the latest in fiber-optics bandwidth. USDCO provides the tech support to keep systems operating.

Wired also carried the story back in 2001. Strangely, the USDCO website is not loading. I’d like to know more about this abandoned mine.
