Great Sand Dunes Partie Trois

This picture taken at the base of the 30 square mile dunefield in Great Sand Dunes National Park.  The sand came from in from the Southwest Winds that blew, bounced, and pushed the grains toward the Sangre De Cristo Mountains piling them into the tallest dunes in North America.  Star Dune is the tallest dune at 750 feet.  One can get an idea of just how large and high it is by noticing the people in the center of the photo.  Nature was working overtime on this beauty.
