The chaotic terrains of Orson Welles Crater host several small-scale (1 to 2 kilometer) long runout landslides. Understanding the origin of terrains and their link with the development of highly mobile landslides is important to unravel the potential role of ice, or other fluids, and so gaining insights into the geological and climatic evolution of this area. These types of small-scale Martian long runout landslides are great analogues of Icelandic landslides.
