Monte Kali: A Mountain of Table Salt

(via Amusing Planet)  Monte Kali is an unusual landmark in the small town of Heringer in eastern Hesse, Germany. It’s a spoil heap containing nothing but sodium chloride or common table salt, which is a byproduct of potash mining. For over a hundred years, potash mining has been a major industry in the region. It started with the opening of Wintershall potash works, which began mining in 1903, and today is the world’s biggest potash mine with an operational area about the size of Greater Munich’s.
