We show that Icelandic long-runout landslides with longitudinal ridges represent good analogues of Martian landforms. The large record of long-runout landslides with longitudinal ridges emplaced after the Last Glacial Maximum in Iceland offers a unique opportunity to study the possible relation between the development of these landforms and environmental conditions. This could have implications for reconstructing Martian paleoclimatic and paleoenvironmental conditions.
