Sister Islands (Wisconsin)

The Sister Islands are two islands in Lake Michigan. They are located in the bay of Green Bay, in the town of Liberty Grove, Wisconsin.[1] At one point the islands were connected, but higher water levels have eroded the size of the islands. Combined, the area of the islands sits at 30.6 acres (12.4 ha). The Sister Islands State Natural Area occupies the space of both of the islands. There are many species of birds that nest on the islands. Both islands are owned and operated by the Wisconsin Department of Natural Resources.[2]
