The Dead Sea – bordering Israel, the West Bank and Jordan – is a salt lake whose banks are more than 400m below sea level, the lowest point on dry land. Its famously hypersaline water makes floating easy, and its mineral-rich black mud is used for therapeutic and cosmetic treatments at area resorts. The surrounding desert offers many oases and historic sites. The evaporation ponds at the south end of the Dead Sea produce both sodium chloride and potassium salts. The pond size, and thus salt production, has expanded substantially in response to global demand for salts used in industrial processing.
