Dunes pictured are at elevation of around 3000 metres (~9850 feet) above sea level, located in western part of the Himalaya Mountains.

Steep valley walls that stick out about 1000–2000 metres (3280–6560 feet) above the valley floor create a narrow corridor. This corridor captures major air mass movements which blow around the sands on the valley floor that eventually make up dunes.

Arch-shaped patters are sand layers within old dunes that have partially eroded. The erosion has exposed the internal structure revealing how the dune was constructed.
