Dunes are formed through the interaction of mountains and wind. The wind picks up quartz grains from the mountains in the area to form the dunes and these are reshaped by the same process over time.
The stovepipe dunes in Death Valley National Park are estimated to have formed over thousands of years, as a result of wind patterns and sand accumulation in the region. The exact duration of their formation is difficult to pinpoint precisely.
Huge piles of sand are called sand dunes. Sand dunes typically form in deserts or coastal areas where there are strong winds that shape and move the sand into these large structures.
Transverse dunes are sand dunes formed across the direction of the winds that prevail in a given area. This is the "normal" way dunes form when winds blow sand across open areas. A link can be found below for more information and to view images.
Desert dunes typically form in arid regions and are characterized by their sandy composition and unique shapes sculpted by wind. Beach dunes, on the other hand, are found along coastlines and are made up of sand deposits from the beach. Both types of dunes play important roles in stabilizing ecosystems and protecting land from erosion.
Sand dunes can form in some areas of the desert, along the coast or near major bodies of water such as the Great Lakes. Some form in areas that were laid bare by the retreat of glaciers after the last ice age.

The stovepipe dunes in Death Valley National Park are estimated to have formed over thousands of years, as a result of wind patterns and sand accumulation in the region. The exact duration of their formation is difficult to pinpoint precisely.
Death Valley has a large amount of salt resulting from thousands of years of water running down the mountains there and washing rock minerals down to the valley below. Over time, the winds have formed the sand there into dunes.
there are also large dune formations inland that are created by similar environmental factors
