Peneus Patera is a feature in the Noachis quadrangle of Mars. It is located at 58.1 S and 307.5 W. It was named after an albedo feature at 48S, 290W.[1]
Scalloped Topography[edit]
Peneus Patera shows what is termed "scalloped topography". Such topography displays depressions with scalloped edges. Sometimes the depressions seem to coalesced together. These features typically occur at about 55 degrees north and south latitude. They are believed to form from the removal of subsurface material, maybe interstitial ice by sublimination (change from solid to a gas). More gentle slopes face in the direction of the equator, while steep scarps face the a pole. This is probably due to differences in solar heating. The process is believed to be still happening at present.[2]
