Singing Sand Dunes | Dunhuang, China

The great desert sand storm. Even the hardiest Silk Road travellers feared it, the camels could tell it was coming, and many never survived it. As if there weren’t enough perils on the road already; vagabonds and thiefs, tireless Turkmen tribes that guarded the sandy desert plains like ocean pirates, suspicious kings and emperors who could throw you into a pit of snakes as soon as you enter their city walls (true story), and then there was Mother Nature herself.
