Great Sand Dunes National Park and Preserve is not as popular as many national parks, but very interesting! It is located in eastern Colorado, near the city of Alamos.

Great Sand Dunes National Park and Preserve is a nature reserve with large sand dunes in the state of Colorado, USA, which was designated a national park in 2004 (and was previously a national monument since 1932). It represents huge areas of wilderness, as well as a more civilized part, where tourists come to see with their own eyes the high dunes of the San Luis Valley and the snow-capped peaks of the Sangre de Cristo mountain range.

Territorially, Great Sands Dunes National Park is located in the high-mountainous desert of Colorado, but from this it is not at all clear how the dunes were formed here.

It is believed that the sand was washed away by streams from the Sangre de Cristo mountains, and was also brought by the Medano stream at a time when there was a lake in the San Luis valley on the site of sand dunes. And with the rise of the Colorado Plateau and turning it into a desert, the lake dried up, leaving washed sand. And the merciless desert winds completed their business, driving sand for thousands of years along their routes back and forth and applying it to a corner formed by nature itself, closed on two sides by mountains.

This is how this epic picture turned out: two mountain ranges, the San Luis Valley and the highest dunes in North America, framed by the Medano Creek.
