North View - Emerald Lake is located in Yoho National Park, British Columbia, Canada. It is the largest of Yoho's 61 lakes and ponds, as well as one of the park's premier tourist attractions. It was discovered in 1882, when famed mountain guide Tom Wilson was led lakeside while rounding up a group of horses that had gone astray, and was immediately taken by the vivid Emerald-coloured waters. | NorthEast View | SouthEast View
