Lake Kliluk

Spotted Lake is very highly concentrated with numerous different minerals. It contains some of the highest quantities (in the world) of magnesium sulfate, calcium and sodium sulphates. It also contains extremely high concentrations of 8 other minerals as well as some small doses of four others such as silver and titanium. In the summer, most of the water in the lake evaporates leaving behind all the minerals. Large “spots” on the lake appear and depending on the mineral composition at the time, the spots will be different colors. The spots are made mainly of magnesium sulfate, which crystallizes in the summer. Since in the summer, only the minerals in the lake remain, they harden to form natural “walkways” around and between the spots.
