Lake Superior Facts
Lake Superior is the largest of the Great Lakes in surface area and volume. All the other Great Lakes plus three more the size of Lake Erie could fit inside Lake Superior. It is particularly known for its clear, cold water, agate beaches and scenic beauty. A circle tour guides highway travelers around the lakeshore. Many shipwrecks in Lake Superior are now protected in bottomland preserves and accessible to recreational divers.
NAME The first French explorers approaching the great inland sea by way of the Ottawa River and Lake Huron referred to their discovery as le lac superieur. Properly translated, the expression means "Upper Lake," that is, the lake above Lake Huron. Kitchi-gummi, a Chippewa Indian translation, signifies Great-water or Great-lake.
