Vibrant fall color at Pictured Rocks National Lakeshore speaks volumes.
Centuries of massive glaciers and battering waves carved the bedrock into these natural works of art. The name "Pictured Rocks" comes from the streaks of mineral stain that decorate the face of the sculpted cliffs. Forty years ago this month, the park became America's first national lakeshore.
Examine the stones along Lake Superior's sandy beaches: horn coral, polished granite, and quartz rounded like eggs.
Red baneberries add sprightly accents to the park's leaf-carpeted trails. But beware: The plant and its berries are poisonous.
Many rivers crisscross the Upper Peninsula, carrying water (and brook trout, Michigan's state fish) to Lake Superior.
Lake Superior encompasses some 32,000 square miles, about the size of Maine. The water would cover the continental United States to a depth of nearly 5 feet.
