Doom Mons is located in the , between 14-15° south and 40-41° west. It is located within the Aztlan darklands region, possibly connected to the wider Shangri-La dark region, and is adjacent to Sotra Patera, a possible cryovolcanic caldera deep. Mohini Fluctus, a bright lobate flow feature at least 200 km long, appears to emerge from Doom Mons and extends to the northeast. It is partially covered by dunes, including at its visible terminus, suggesting it is on the order of tens of meters thick. About 470 km to the north-northeast is situated another putative cryovolcanic feature, Erebor Mons, which is 40 km across, over 1 km high, and has lobate flow features to its north and east.
