Native American name

A Native American name for the island is Mah-ko-me-ne-shine-me-nis or "Bear Island". A legend published in the early 1900s relates an incident four hundred years prior where a spirit bear was seen crossing the lake from the east shore. The Potawatomi beckoned him ashore. Since then they call the island Old Bear Cub island.[5]
