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.
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.
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.
Death Valley is a land form in itself and is a deep gorge where the earth has shifted apart from one another. Death Valley is a harsh place to live with mountains, sand dunes and flooded canyons.
Erosion primarily formed Death Valley by carving out the landscape over millions of years. Deposition also played a role in shaping some features within the valley, such as sand dunes, but erosion has been the dominant force in creating the overall topography of the area.
there are also large dune formations inland that are created by similar environmental factors

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.
