Martian Mega-Ripples

Mega-ripples are distinct wind-driven formations that occur on the surface of Earth and Mars, often with sizes between that of smaller ripples and larger dunes. Based on their shapes and examples of fractured crests in some areas, mega-ripples are thought to be largely inactive relics of past climates
