Here is a drone video that was taken in Osoyoos, BC in the Fall 2017 while we were driving across Canada from East to West in our modified school bus.
Spotted Lake is richly concentrated with various minerals. It contains dense deposits of magnesium sulfate, calcium and sodium sulphates. It also contains high concentrations of eight other minerals and lower amounts of silver and titanium. Most of the water in the lake evaporates over the summer, revealing colorful mineral deposits. Large “spots” on the lake appear and are colored according to the mineral composition and seasonal amount of precipitation.
Amazing natural formation !!
