Cerberus Falls is an absolute colossus of a waterfall situated at the head of spectacular Icefall Canyon, deep in the Canadian Rocky Mountains. The falls occur as Icefall Brook emerges from its source in the Southwest Lyell Glacier and hurtles over the edge of the glacially scoured trough. Depending on the daily temperature and the time of year, there can be anywhere from two to four main streams of water pouring over the canyon and forming the falls. The standard display consists of three segments grouped closely together, with a fourth major segment located a short distance to the southwest. What makes Cerberus Falls truly stand out from other waterfalls of similar size in Canada is the volume of water involved. On an average summer day the Lyell Glacier can send as much as 400-600 cubic feet of water flowing over the falls every second. However, on days when the temperature pushes 90° F, the volume of water can swell to closer to 1000 cubic feet per second.
