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: Ono što se dešava je da vetar nanosi pesak uz blažu padinu na drugoj strani, a zatim, kako zrno po zrno stiže do vrha strmine, ono stepenasto pada dole, u unutrašnjost "polumeseca", i tako se cela dina u obliku rogova kreće.
