The tallest sand dunes in North America are the centerpiece of Great Sand Dunes National Park and Preserve. They rise in places more than 750 feet (229 m) from the floor of the San Luis Valley, on the western slopes of the Sangre de Cristo Range in western Colorado.
When I visited the area was still a national monument. It obtained national park status in 2004. The view was superb in May, 1990, but my shorts now look woefully outdated. My good friend Mike Muhr took this picture during a weekend hiatus from Colorado School of Mines field geology camp.
