In the present day, Mars' mid-to-high latitudes host abundant water ice within diverse glacial landscapes, including in buried glaciers. In this talk, we will explore the recent history of glaciation on Mars and its place within the story of water on the Red Planet. Have Mars' glaciers always been frozen under stubbornly cold climate conditions, or did they ever produce meltwater? I will present recent discoveries which suggest some of Mars' glaciers produced meltwater at their beds (at least transiently) and explore the implications for the recent thermal environment on Mars.
