HiPOD 3 Aug 2022: Not Your Typical Pit Crater
Atypical Pit Craters (APC) are concentrated mostly in the Tharsis region of Mars. A small collection of APC has been identified near Elysium Mons. APC are generally cylindrical or bell shaped with long lived vertical or overhanging walls. APC examples in much older terrain should reveal erosional characteristics and possibly whether they are ancient or formed more recently.
