Groundwater on Mars

The preservation and cementation of aeolian dune stratigraphy in Burns Cliff in Endurance Crater are thought to have been controlled by flow of shallow groundwater.[1]

Rain and snow were regular occurrences on Mars in the past; especially in the Noachian and early Hesperian epochs.[2][3][4][5][6][7] Water was theorized to seep into the ground until it reached a formation that would not allow it to penetrate further (such a layer is called an aquitard and is believed to be impermeable). Water then accumulated forming a saturated layer. Deep aquifers may still exist.[8]
