Emerald

Emerald Lake is located in Yoho National Park, British Columbia, Canada. It is the largest of Yoho's 61 lakes and ponds. The first non-indigenous person to set sight on Emerald Lake was Canadian guide Tom Wilson, who stumbled upon it by accident in 1882."For a few moments I sat on my horse and enjoyed the rare, peaceful beauty of the scene." It was Wilson who gave the lake its name because of its remarkable color, caused by fine particles of glacial sediment, also referred to as rock flour, suspended in the water.
