Bill Peyto (pea-toe) was a trapper and guide in Banff and the Canadian Rockies in the late 1800's. This lake was named after him and has become one of the main attractions for photographers and visitors alike. The lake gets it's color from the rock dust and particles. The dust suspends in the lake and when the sun reflects off the dust appears turquoise in color. The best time to get the full effect of the emerald color is when the sun is directly overhead.
