The Pictured Rocks National Lakeshore Lake Superior

Near Grand Marais, Michigan there are high sandstone cliffs called the Pictured Rocks that stretch for 38 miles.  I took a boat trip along this shore and saw a pair of peregrine falcons that had a nest on top of the rocks.  This was a great spot for them to dive upon their prey.

I could hear the sound of waves thundering in the caves at the base of the cliffs.  The soft sandstone of the Pictured Rocks was formed when saltwater seas covered much of the continental United States millions of years ago.  Later, the powerful wave action of Lake Superior carved the stone into many beautiful shapes: one resembles a castle, others three battle ships, two indian drums, a broken flower vase, and the profile of an indian's face.  The buff colored rocks are steaked with green, red and black caused by deposits of copper, iron, and other minerals along with white limestone.

The Pictured Rocks are covered on top with forested sand dunes.  In the Grand Marais area there are waterfalls to explore.
