Michigan, Lake, a long piece of water between Wisconsin and Michigan, joins Lake Huron between St. Ignace and Mackinaw. The name, which is Indian in origin, and means "Great Lake," was at first applied both to Huron and
Michigan, as they properly form but one lake.
Michigan proper is 335 miles long, and varies from 50 to 90 miles in breadth. On the low shores are numerous lighthouses, and there are several harbours on the western coast. Mean depth of lake 325 feet.
