Mysteries of the Great Lakes

Lake Superior

  • Is the largest of the five Great Lakes of North America.
  • Its northern boundary is in Ontario, Canada and Minnesota, USA, and its southern boundary is the U.S. states of Wisconsin and Michigan.
  • Is the largest freshwater lake in the world by surface area and is the world's fourth-largest freshwater lake by volume.
  • Alone holds as much water as all four of the other Great Lakes combined.
  • Has a surface area of 31,820 square miles.
  • Has a maximum length of 350 miles and maximum breadth of 160 miles.
  • Has an average depth of 483 feet with a maximum depth of 1,333 feet.
  • Contains 2,900 cubic miles of water—the equivalent of 3 quadrillion (3,000,000,000,000,000) gallons.
  • Is large enough to have room for every man, woman, and child on Earth to spread out a 12' x 12' picnic blanket on its surface if entirely frozen (which has happened only twice in recorded history).
  • Is the final resting place for 350 ship wrecks.
