Salt Lake City's Namesake: The Great Salt Lake as a Salt Source

Salt Lake City is named after the Great Salt Lake, a massive terminal lake west of the city. The lake's salinity (5–27%, vs. ocean's 3.5%) comes from mineral-laden rivers (Bear, Weber, Jordan) flowing in with no outlet—water evaporates, leaving dissolved salts behind.

Salt Production

• Native Americans (Ute, Shoshone) harvested salt for centuries.
• Mormon pioneers (1847) began commercial production.
• Today: Compass Minerals operates solar evaporation ponds producing ~2M tons/year.

Uses

• Industrial: Water softening, road de-icing, chemical feedstock.
• Food: Canning, curing, some table salt (after refining).

While not the world's only lake salt source (Chile's Salar de Atacama, Australia's Lake Tyrrell are larger), the Great Salt Lake is a significant U.S. supplier and a unique ecological and economic asset.
