As a father’s day gift to himself, Dad took Guinevere and I on the Pictures Rocks national shoreline tour. The Pictured Rocks cliffs tower 50 to 200 feet above Lake Superior, the colorful sandstone cliffs stretch for about 15 miles along the lake. Their name comes from streaks of mineral stain that decorate the weather sculpted sandstone. Colors of red, orange, blue, green, brown, black and white occur when ground water oozes out and trickles down the rock face. The most common color-producing minerals are; iron, copper, manganese and limonite. In-spite of it being mostly overcast that morning, we saw amazing views of the rock sculptures, waterfalls and cedar trees.
