February 7, 2017 -- Emerald Lake
Aptly named, Emerald Lake in the southern Yukon, notable for its intense green color. It is located on the South Klondike Highway between Whitehorse and Carcross, Yukon Territory.
The color derives from light reflecting off white deposits of marl, a mixture of clay and calcium carbonate, at the bottom of the shallow waters.
The high concentration of calcium carbonate in the water here comes from limestone gravels eroded from the nearby mountains and deposited here 14,000 years ago by the glaciers of the last ice age. Glacial erosion was likewise responsible for scooping out the shallow lakebed.
