AMERICAN ROCK SALT is the largest operating salt mine in the United States with a capacity for producing up to 18,000 tons each day. Established in 1997, this underground salt mine is the only one built in the United States in the last 40 years.

These deposits are usually the remains of inland seas that evaporated thousands or millions of years ago.

The primary difference between rock and table salt is the size. Rock salt forms in very large, chunky crystals, as opposed to the small crystals seen in table salt.

At home, people often use rock salt when they make ice cream. When it's packed in with ice in an ice cream maker, it lowers the freezing point, allowing the ice cream to get colder.
