SALT AND SKY: The remote Salar de Uyuni salt desert in Bolivia is a land of extremes (freep.com): Report of a trip through the salt apn. "Salar de Uyuni is the largest salt flat in the world, roughly 25 times the size of the Bonneville Salt Flats in Utah. Some 40,000 years ago, it was part of Lake Minchin, a prehistoric salt lake. Today it is a popular tourist attraction for its natural wonder, salt islands and a now-closed hotel made almost entirely of salt."
