  1. Since the San Luis Valley is such a windy area, it is easy to experience the dune-building process firsthand. (Word to the wise: wear long pants, as your legs may get hit by flying sand and rocks during your hike.)

  1. Parts of the Sand Dunes are made up of black sand, which is composed of the mineral magnetite.

  1. Any guesses as to how much sand there is at the Dunes? Believe it or not, there is an estimated 5 billion cubic meters of sand within an area of 30 square miles.

  1. In addition to protecting the unique area, the Great Sand Dunes were designated as a National Park in order to shield the extra water located just inches below the sand.
