The sculpted sandstone cliffs that line Lake Superior's south shore are a national treasure, and that's why the U.S. Congress designated the area as a National Lakeshore back in 1966. As our country's first National Lakeshore, the Pictured Rocks area attracts over half-a-million visitors each year.
When you take a boat tour of the Pictured Rocks, one of the first things you'll notice is that the cliffs are streaked in a variety of rich colors. These stains are caused by mineral-laden groundwater leaching out of the rock.
Iron creates rust-red streaks while manganese is responsible for the black stains. Green and blue streaking comes from copper and white represents the calcium content in lime.
