From the dawn of civilization to today, MODERN MARVELS shows how man collects the humble mineral that is essential to human life.
Salt is the most humble and precious of minerals. In Roman times, soldiers were sometimes paid with it. In the Middle Ages, it was called "White Gold." Today, we collect 146 million tons of salt annually, and it is used in over 14,000 ways.
MODERN MARVELSTM journeys beneath the earth to tell the extraordinary story of how we collect this essential mineral--and of the awesome caverns salt mining creates.
Visit a 700-year-old mine in Poland that has three chapels and a soccer field among its underground chambers. Sea salt has been collected over the millennia, from dehydrating sea water to scratching it out of underground chambers. And take a fascinating step-by-step trip backwards from the salt shaker on your dinner table to the strange, subterranean world of a modern salt mines.
From a Manhattan-sized mine near Cleveland to the world's largest underground storage facility, SALT MINES tells the story of the staff of life and the amazing places created by its collection.
