Went to see McGulpin Rock by Mackinaw City - dates back to 1615

McGulpin Rock (west of Mackinaw City, on the shore of Lake Michigan) is 5 times the size of the Pilgrim's Plymouth Rock and dates 5 years before the Pilgrims even arrived on the Mayflower... but it doesn't get as much publicity! Native tribes used this huge rock to guage the rise and fall of the Great Lakes. It is 9 feet tall and weighs an estimated 54 tons We walked right up to this really big, old rock and took pictures.
