Salt production has been integral to the development of the United States, with a rich history dating back to the Native American tribes who first harnessed this valuable resource. Early reports from Onondaga, New York, in 1654, indicate that the Onondaga Indians produced salt by boiling brine from natural salt springs. This method of salt production was later adopted by Colonial Americans, who used iron kettles to boil brine during the drafting of the U.S. Constitution. By the Civil War, this method had evolved, with thousands of workers producing over 225,000 short tons of salt annually through boiling.

Early Salt Production Sites

• Kanawha, West Virginia: Before 1755, Native Americans were reported to produce salt here by boiling brine from salt springs. Large-scale production from these brine springs began by 1800, with drilling for more concentrated brine commencing soon after. During the Civil War, the Kanawha Valley became a crucial supplier of salt for the Confederacy, with production peaking during this period.
• Avery Island, Louisiana: Historians believe that Native Americans were producing salt here more than 500 years before Europeans arrived. This region supplied salt during the War of 1812 through brine boiling. Full-scale production began during the Civil War in 1862, and the first underground salt mine was established in 1869.

Advancements in Salt Production Techniques

• Solar Salt Production: In the early 1800s, solar salt was produced even in less-than-ideal climates by building movable, covered sheds over evaporating pans to protect the salt and brine from precipitation. This method was utilized in San Francisco Bay, California, starting in 1770, and at the Great Salt Lake in Utah by 1847.
• Mechanical Evaporation: Around 1833, mechanical evaporation in multiple-effect open "grainer" pans began, along with methods to purify the brine before evaporation, producing a clean, white salt product. Innovations at Silver Springs, New York, during the 1800s, led to the development of crystallizing salt in enclosed vacuum pans.

Widespread Salt Production Between 1790 and 1860, salt was produced across various states including Louisiana, Michigan, Ohio, Pennsylvania, Kentucky, Indiana, Illinois, and Missouri by boiling brine in salt furnaces. Michigan's Saginaw and St. Clair regions became significant producers in the mid-1800s, utilizing waste wood products from the lumber industry as low-cost fuel. The discovery of a rock salt deposit at St. Clair in 1882 further advanced the industry, allowing for solution mining and the spread of this technology across salt-producing states.

Modern Salt Mining in North America Today, salt mining continues across North America, in regions such as Kansas, Louisiana, Ohio, New York, Texas, Ontario, New Brunswick, Quebec, and Nova Scotia. Kansas, Utah, Louisiana, New York, Ohio, and Michigan have seen their local histories and cultures enriched by salt production. Notably, the branding by Morton Salt has made it a household name in American commerce, and the long-standing tradition of salt mining under the city of Detroit, Michigan, remains a testament to the industry's enduring importance.
