Some dark fans on icefields the result of small meteorite impacts?

• by Puffcrumb

  This is my first discussion entry on this site. However, after having attempted to classify a fair number of images I have noticed more than once on otherwise white ice sheets an apparent correlation between what appears to be small craters at the start of black win-blown fan trails. Is it possible that in addition to pressure build up and natural fissures in the ice providing exit points for debris-filled fan plumes - sometimes small meteor impacts may instigate such eruptions?

  Most probably you are talking about boulders. There is example in FAQs and lot's mot in discussions.
