Discover the secrets behind this Canadian lake that looks like something from another planet.
Why? Super-concentrated minerals! As water evaporates, colorful, circular pools are left behind.
What's In It? Mainly magnesium sulfate (Epsom salts), plus calcium, sodium, and even traces of silver and titanium.
Like a Mood Ring! Color of the spots depends on the mineral mix in a given pool and the season.
History: First Nations peoples used the lake for healing. It's considered a sacred and medicinal place.
Flashback: During WWI, minerals from the lake were used in ammunition manufacturing.
Caution: The unique geology and chemistry make the lake sensitive to pollution and overuse.
Weird World: Similar 'spotted' lakes exist in a few other places globally but with different mineral mixes.
