But why not mix things up by giving your father a stone found in Michigan's lower peninsula, the Petoskey stone. Due to the unique presence of Petoskey stones in Michigan, they were named the Michigan state stone in 1965. The Petoskey stone, along with the name of the city of Petoskey, Michigan, name comes from an Ottawa Indian Chief, Chief Petosegay. Perhaps the largest Petoskey stone ever found was reported in September of 2015 when a 93-pound Petoskey stone was discovered along the shores of Lake Michigan. So, if you're in a last-minute ditch effort to buy your dad a Father's Day gift, consider a Petoskey stone from Michigan.
