Huron Island Light is a lighthouse on Lake Superior near Big Bay, Michigan. It was listed on the National Register of Historic Places as Huron Islands Lighthouse in 1975. The light station is a duplicate of the one built at the same time on nearby Granite Island. Other sister designs include Gull Rock and Marquette Harbor lighthouses. The station is 1½ stories tall and built from granite, with a square light tower, 39' in height, integrated into the structure. The original light was an decagonal cast iron lantern with a 3½-order Fresnel lens. Today it is owned by the United States Fish and Wildlife Service. Eagle Harbor Light is a lighthouse near Eagle Harbor Township, Michigan on the Keweenaw Peninsula jutting from the Michigan's Upper Peninsula up into Lake Superior. This area of Michigan is often referred to as Copper Country, and sometimes as Copper Island. In 1999 the Congress of the United States transferred ownership of the Eagle Harbor Light Station to the Keweenaw County Historical Society, which operates the lighthouse as a museum. The Coast Guard continues to operate the light at the top of the tower. The Keweenaw Lower Entry lighthouse is located at the end of a breakwater on the eastern side of the entrance to the Portage River near Jacobsville, Michigan.
