Salt

In Kansas, salt is found in thick beds deep underground. The thickest and most extensive salt layer in Kansas is the geologic formation known as the Hutchinson Salt Member, which underlies approximately 37,000 square miles of central Kansas. About 500 to 1,000 feet deep in much of Kansas, it is, on average, 250 feet thick.

Underground mining started in Hutchinson in 1923, and salt is still mined in Hutchinson, Kanopolis, and Lyons.
