✔ it contains as much water as all the other Great Lakes combined, plus three extra Lake Erie’s!

✔ there is a small outflow from the lake at St. Mary’s River (Sault Ste Marie) into Lake Huron, but it takes almost two centuries for the water to be completely replaced.

✔ there is enough water in Lake Superior to cover all of North and South America with water one foot deep.

✔ Lake Superior was formed during the last glacial retreat, making it one of the earth’s youngest major features at only about 10,000 years old.
