Fine scale beds exposed on the floor of Holden crater were likely deposited in an ancient lake. Persistence of such a lake points to conditions that would have been much more clement that currently are found on Mars and may point to habitable conditions early on in the planet's history. Portion of HiRISE image PSP_003077_1530_IRB showing eroded alluvial fan materials overlying phyllosilicate bearing, probable lacustrine deposits in Holden crater, Mars. False color created using data from the RED (image scale of 26 cm/pixel), IR, and BG CCDs (image scale 52 cm/pixel) on the HiRISE camera. Scene is approximately 750 m across and north is up.
