In the late 17th century, Diego de Vargas, a Spanish governor of Santa Fe de Nuevo Mxico, became the first European on record to enter the San Luis Valley. [10], While the top few inches of the dune field are often dry, the dunes are moist year-round due to ongoing precipitation. Sand surface temperatures peak at 150F (65 degrees C) on a sunny summer afternoon and drop to -20F (-29 degrees C) on a winters night. With these two mountain ranges in place, the San Luis Valley was born, covering an area roughly the size of the state of Connecticut.Sediments from both mountain ranges filled the deep chasm of the valley, along with huge amounts of water from melting glaciers and rain. [53] The IUCN has included the same 51 square miles (132km2) of dunes and surrounding sand sheets on their global list of wilderness areas (management category Ib) since 1976.

The sabkha forms where sand is seasonally saturated by rising groundwater. He was followed in 1853 by Captain John Gunnison of the Corps of Topographical Engineers. [10], The park preserves the tallest sand dunes in North America,[7] as well as alpine lakes and tundra, mountain peaks over 13,000 feet (3,962 m) in elevation, mixed conifer forests, grasslands, and wetlands. Other features include snow-fed creeks originating high in the mountains, and several alpine lakes. Each day, sand erodes from surrounding mountains and is carried by wind and water to the dunes.

We have since learned that the dune sand extends hundreds of feet into the subsurface, so they are older than initially believed. Some of these migrating dunes become covered by grasses and shrubs and stop migrating. Lake Alamosa suddenly receded after it broke through volcanic deposits in the southern end of the valley. The mountain watershed receives heavy snow and rain which feeds creeks that flow down from alpine tundra and lakes, through subalpine and montane woodlands, and finally around the main dunefield. [12], Big Spring Creek is a unique spring-fed creek formed by an unconfined aquifer that creates wetlands that support rare species and plant communities in a generally arid area. Just as our own voices are made by air moving through vibrating vocal chords, a humming sound is made at Great Sand Dunes as air is pushed through millions of tumbling sand grains during an avalanche. What will bring you? These smaller bodies of water and seasonal lakes helped sort the sand from the rest of the sediment.
