Spotted Lake (Kliuk) in Canada

Spotted Lake (Kliuk), situated in Osoyoos, Canada, is a rare and unique natural phenomenon covering 15.2 hectares (38 acres). It contains one of the world’s highest concentrations of minerals: magnesium sulphate (Epsom salts), calcium and sodium sulphates, plus eight other minerals and traces of four more, including silver and titanium. The Indians soaked away aches and ailments in the healing mud and waters of the spotted lake. In the hot sun of summer, the water of Spotted Lake evaporates and crystallizes the minerals, forming many white-rimmed circles: shallow pools that reflect the mineral content of the water in shades of blues and greens.
