This photo tells the story behind my shot of the sunrise on top of Dune45 in the Namib, the world's oldest desert. The wind constantly blows the sand over the edge of the dune, giving it its unique shape and keeping it in place. The wind blows equally often and strong from West and East, making the dune itself immovable. I was thrilled by the thought of how many millions of grains of sand are blown over the edge of this and all the other dunes in the desert every second. This photo captures a few of them in flight.

The lower falls at Yellowstone National Park are 308 feet (94 meters) high, or almost twice as high as Niagara. They descend from the 590,000 year old Canyon Rhyolite lava flow and are the largest volume major waterfall in the Rocky Mountains.
