Ancient carvings and Michigan's quietest coast

In a quiet stretch of woods in Greenleaf Township, a sandstone outcrop carries something found nowhere else in Michigan: the Sanilac Petroglyphs, the state’s only known Native American rock carvings. Etched centuries ago — archers, handprints, spirals, and the water panther Mishibizhiw — the carvings survived weather and time, and are now protected as a historic state park co-stewarded with the Saginaw Chippewa Indian Tribe, with summer tours that bring the stories to life.

The county around them is the Thumb at its most unhurried: some forty miles of Lake Huron shoreline along M-25 where sunrise beats sunset every day, harbor villages like Lexington and Port Sanilac with their lighthouses, marinas, and summer concerts, and farmland running to the horizon behind them. Sanilac is the coast Michigan forgot to crowd — the locals consider that the whole point.
