english: What happens is that the wind blows the sand up the shallow slope on the other side, and then, as each sand grain hits the top of the ridge, it cascades down on the inside of the crescent, and so the whole horn-shaped dune moves.
non_english: Deje sa to, že vietor ženie piesok hore miernym svahom na druhú stranu a keď zrnko piesku dosiahne vrchol hrebeňa, skĺzne po vnútornej strane polmesiaca, čím sa posúva celá duna.
