Lake Superior facts

Thought this might be an interesting perspective to folks that can't comprehend the enormity of the Great Lakes.

Lake Superior contains ten percent of all the fresh water on the planet Earth.

It covers 82,000 square kilometers or 31,700 square miles.

The average depth is 147 meters or 483 feet.

There have been about 350 shipwrecks recorded in Lake Superior

Lake Superior is, by surface area, the largest lake in the world.

A Jesuit priest in 1668 named it Lac Tracy , but that name was never officially adopted.

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.

The deepest point in the lake is 405 meters or 1,333 feet.

There are 78 different species of fish that call the big lake home.

The maximum wave ever recorded on Lake Superior was 9.45 meters or 31 feet high.

If you stretched the shoreline of Lake Superior out to a straight line, it would be long enough to reach from Duluth to the Bahamas .

Over 300 streams and rivers empty into Lake Superior with the largest source being the Nipigon River

The average underwater visibility of Lake Superior is about 8 meters or 27 feet, making it the cleanest and clearest of the Great Lakes . Underwater visibility in some spots reaches 30 meters.

In the summer, the sun sets more than 35 minutes later on the western shore of Lake Superior than at its southeastern edge.

Some of the world's oldest rocks, formed about 2.7 billion years ago, can be found on the Ontario shore of Lake Superior

It very rarely freezes over completely, and then usually just for a few hours. Complete freezing occurred in 1962, 1979, 2003 and 2009.

It would take 22.3 quadrillion packets of Crystal Light On The Go to turn the big lake they call Gitche Gumee into lemonade, requiring the Great Lakes' largest bulk freighter, M/V Paul R. Tregurtha, to make 1.5 million trips to carry the 98.8 billion tons of drink mix needed to do that.
