From Openwaterpedia
Lake Michigan is one of the five
Great Lakes of North America and the only one located entirely within the United States. The other four
Great Lakes are shared by the US and Canada. It is the second largest of the
Great Lakes by volume and the third largest by surface area, after
Lake Superior and
Lake Huron. Hydrologically, the lake is a large bay of Lake Michigan-Huron, having the same surface elevation as
Lake Huron (among other shared properties). It is bounded, from west to east, by the U.S. states of Wisconsin, Illinois, Indiana, and Michigan. The word "Michigan" originally referred to the lake itself, and is believed to come from the Ojibwa word mishigami meaning "great water".
Marathon Swimming
It is site of the annual 2.5 km and 5 km Big Shoulders race in September and the professional marathon swims of the early 1960's where swimmers like Ted Erikson and Greta Andersen competed against the world's best swimmers.
