Evidence of an eolian ice-rich and stratified permafrost in Utopia Planitia, Mars

► Scalloped depressions occur in an ice-rich permafrost. ► We propose that scalloped depressions reveal tilted sedimentary layers. ► The 52 studied layers have different shallow dips. ► The layers show different resistance to degradation due to different ice-content. ► The permafrost stratification is complex and indicative of eolian sediments.
