Periglacial mass-wasting landforms on Mars suggestive of transient liquid water in the recent past: Insights from solifluction lobes on Svalbard

► Superposition relationships of landforms suggest a young age for the lobes. ► Morphometric relationships and morphology suggest a solifluction origin. ► Solifluction-like lobes may indicate transient liquid water within the regolith. ► Freeze-thaw induced mass wasting may have been a common process.
