image creditSpotted Lake is a saline endorheic alkali lake located northwest of Osoyoos in British Columbia, Canada. Spotted Lake is very highly concentrated with numerous different minerals. It contains some of the highest quantities of magnesium sulfate, calcium and sodium sulphates.
Most of the water in the lake evaporates over the summer, 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. In the summer only the minerals in Spotted Lake remain, and they harden to form natural walkways around and between the spots.The Presurfer
