Have you ever wondered how or even why Kalamalka Lake turns an emerald green every summer?
Tourism Vernon has the answer. In a Facebook posting, the organization explains that the green colour is because of limestone deposits left by receding glaciers.

“When the lake warms in the summer, dissolved limestone crystallizes, giving the lake a distinctive blue and green hue,” wrote Tourism Vernon.
When the lake cools again, the limestone crystals disappear, taking the green colour with it.

BC Parks echoes the explanation. Posted on the government website, they explain that Kalamalka Lake is one of only a handful of unique bodies of water known as “marl lakes.”
"When the lake warms in the summer, calcium carbonate, or limestone, forms crystals that reflect sunlight and create its distinctive blue and green colours," said BC Parks on its website.
