In south central Colorado on the eastern side of the San Luis Valley are the
Great Sand Dunes, the tallest sand dunes in North America. The dunes cover
approximately 39 square miles and rise to almost 750' above the valley floor.
The dunes are the product of the wind and rain eroding the San Juan and Sangre
de Cristo Mountains. Over the course of millenia, the dunes have built up to
where they are today, and tomorrow they will be different because the wind still
blows, the sand still moves and the deposits of sand still grow. The dunes are
like continually changing sculptures. |
