Little Limestone Lake is the world’s largest example of a marl lake, which is a calcium carbonate-rich lake. When it’s warm out, the marl forms into calcite and separates from the water, which creates crystals and leads to the turquoise hue in the water (what you find in the Caribbean). As it cools off though, the calcite dissolves which decreases the marl level and turns the water crystal clear. Throughout the year the lake will change colours, and hence the view depends on the time of the year.

There is nothing little about Little Limestone Lake as it is around 15 kms long and approximately around 4 kms in width.

The Little Limestone Lake is actually a Provincial Park (...). - in: https://www.todocanada.ca
