Kliluk, the Spotted Lake (Canada)

In the hot sun of summer, the water of Spotted Lake, located in British Columbia and Washington, 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. It contains one of the worlds 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. One story cites a truce in a battle to allow both warring tribes to tend to their wounded in the Spotted Lake, "Kliluk".
