Lake Michigan is one of the five Great Lakes of North America, and the only one in the group located entirely within the United States. It is bounded, from west to east, by the U.S. states of Wisconsin, Illinois, Indiana, and Michigan. For a brief period, the informally named Justice League Detroit used a secret tunnel beneath the lake to access the Justice League Bunker.
Lake Michigan is one of the five Great Lakes of North America, and the only one in the group located entirely within the United States. It is bounded, from west to east, by the U.S. states of Wisconsin, Illinois, Indiana, and Michigan. The word "Michigan" was originally used to refer to the lake itself, and is believed to come from the Ojibwa Indian word mishigami, meaning "great water."
