    I thought, I repeat myself here too:
    It's very hard to understand what this is when it's covered by ice and maybe dusty fan. We have not observed this feature at the time when there is no ice cover. I have just put new request to do so, hopefully we will have a look at it soon.

    Many thanks Anya, I'm thinking it looks like the cone of a gas eruption, with black material falling to the right (I think I see a white gas jet on the same side). I hope it is, it is by far the most exciting pic of the bunch.....so far!

    Hi, could you tell me how thick you would expect the ice to be here? Also, could a rock protruding from the surface underneath the ice cause a weakness in the ice resulting in a conical crater? Maybe with a glimpse of the tip of the rock inside the crater, partly obscured by the gas jet and its debris?

    Ice layer is not more than a meter, most probable 1/2m. Can not say more precise.
    If we get ice-free image, we might be able to clear up if your hypothesis is correct. It's not impossible 😃
