REDMOND -- Mark Bosshardt has spent eight years in the deep, dark tunnels beneath the small, central Utah town of Redmond.
He's not mining for precious metals or coal.
It's all about the salt, deemed by some as the "greatest salt on earth" because of its ability to melt at much lower temperatures.
Redmond Trading Company will produce 12,000 tons of the pinkish salt a week -- most of it used to make icy roads safer, KSL reports.
The salt deposit beneath the town is estimated to be about 3 miles long, one-quarter of a mile wide and roughly 5,000 feet deep.
At this rate, there's enough material to mine for hundreds of years, if not a couple thousand.
Much of it is used in the West on the roads, but it's more than road salt.
Its table food name is Real Salt, because it is all-natural, from an ancient seabed geologists date to the Jurassic Era.
"We try to leave it just the way nature created it, without adding any chemicals or anti-caking agents, without taking any minerals away," said Darryl Bosshardt, sales manager for Redmond Trading Company.
They just mine it, haul it, crush it, bag it and ship it, sometimes across the world.
"You can go to Japan, Taiwan, Hong Kong, and there is a salt from deep within the earth in Utah that finds its way onto the grocery store shelves in Taipei," Darryl Bosshardt said.
That's a source of pride to miners such as Mark Bosshardt, who calls the tunnels home.
"It's kind of humbling to see how far that (salt) has actually (gone)," he said.
