When my family and I did a road trip to Banff last summer, we stopped by Emerald Lake in Field, BC. Located in Yoho National Park, Emerald Lake is the largest of Yoho’s 61 lakes and ponds. The lake was discovered in 1882 during the construction of the Canadian Pacific Railway when Tom Wilson, a well-known guide, stumbled upon this hidden gem.
The impressive hue comes from silt-like rock flour which moves into the lake by melt-water from the surrounding glaciers. The sunlight that reflects off the silt is what gives Emerald Lake that beautiful turquoise blue or green color. Will we be back in the Yoho National Park.
