In 1923, the Carey Salt Company in Hutchinson, KS dropped a mine shaft 650 feet below the earth’s surface to tap into a large salt deposit. This salt deposit, formed 275 million years ago, is one of the world’s largest and spans much of Kansas, Oklahoma and Texas. The mine has been in continuous operation since it opened, changing ownership a few times. The mine is now owned by the Hutchinson Salt Company and it yields about 5,000 tons of salt every day, most of it used for ice-melting applications and various other industrial and agricultural purposes. Table salt, also produced in this region though not at this mine, is extracted in a very different process that involves pumping fluids down to the salt layer to dissolve salts and pumping the solution back to the surface for refining.
There are 14 other salt mines in the US. The only mine that offers underground tours is this one in Hutchinson – the Kansas Underground Salt Museum – which is now run by a non-profit educational foundation called Strataca.
