Geomorphological characterisation and interpretation of a mid-latitude glacier-like form: Hellas Planitia, Mars

► Detailed characterization of an Alpine-type valley glacier or glacier-like form (GLF) on Mars. ► Lower basin landforms are consistent with wet-based glaciation. ► Two surface terrains may show signs of current erosion by intermittent surface water. ► GLF has responded dynamically to climate change in the recent past. ► GLF basin currently characterized by 'active' upper basin and lower basin of relict subglacial bedforms - similar to Earth.
