Munising, Michigan invites you to come and discover the Pictured Rocks National Lakeshore. Comprised of colorful weathered sandstone, The Pictured Rocks National Lakeshore is an ongoing work of art created by Mother Nature. Trace minerals seep from the cracks of the sandstone leaving distinct color stains from different minerals. Then with the help of wind, lake water, rain, snow, lightning, and hail – the rocks are eroded and sculpted into their current forms. Come and experience the majesty and wonder of the Pictured Rocks up close.
