The Khongor dunes are known as the “singing sands” because when the wind blows over them it makes strange sound like the high-pitched tone of an aeroplane engine about to take off or land. These dunes are largest accumulation of sand in the Gobi Gurvan Saikhan National Park, covering 965 km². They rise sharply from the plain reaching a height of 800 m and extending for 150 km witha width of  6-12 km.

The spectacular dunes are bordered by lush green vegetation supported by the Khongoriin Gol, a small river which is fed by underground sources from surrounding mountains. Swept into constantly varying shapes by the wind, parts of their attraction is the impressive colors that the yellow-white sands take on with the changing light of day.

These horses started off the morning grazing on lush grass near a small stream, so I followed to take a few pictures. Something about the interplay between the rich browns of their coats and the desert sands fascinated me.
