What are the Pictured Rocks?

0

The Pictured Rocks are sandstone cliffs rising 50 to 200 feet directly up from Lake Superior. The cliffs begin just east of Sand Point and stretch for about 15 miles. Mineral seepage creates the colors. Red and orange are iron, green and blue are copper, black is manganese, and white is lime.
