Pingo like structure - rarity

• by JellyMonster

  Bit out of touch but I have only encountered one pingo like structure on the Martian surface - why just the one?

  Hi there Jellymonster, suggest you pop over to P4 terrains and look up a few "conical mounds"

  Great images thanks wassock. So all these 'limpets' are related to the Paul Johnson's solitary 'Space Chimney'?

  Don't think so - the chimney turns out to be a hole, and there seem to be several species of limpet on different types of terrain, so may have different causes.
