A common crescent-shaped dune with horns pointed downwind is called a barchan dune.
A barchan or barkhan dune is a crescent-shaped dune. Barchan ("BAR-kahn") dunes form in areas with only one wind direction, and little or no vegetation. If conditions were "perfect"—the landscape was flat, winds blew from only one direction, vegetation could not grow, and sand was available but limited —barchan dunes would dominate a sandscape. One of the commonest types of dunes, it occurs in sandy deserts all over the world. Barchans are mostly formed by the wind from one direction and appear convex. They are arc-shaped, significantly asymmetrical in cross-section, with a gradual slope towards the wind sand ridge, and made out of well-sorted sand.
