This stock photo includes the Aguasabon Falls near the town of Terrace Bay during a spring flood, Lake Superior, Ontario, Canada. The Aguasabon River originates at Long Lake and empties into Lake Superior. The Aguasabon is 70 kilometres (43 mi) in length, and plunges down 30 metres (98 ft) at Aguasabon Falls near Terrace Bay. The river follows fractures in the 2.6 billion-year-old bedrock, and the exposed rock is granodiorite.
