    I think you'll find they're crater impacts.

    These a boulders. They stick out of the ice layer and get warm faster than the ice around them. Only the ice that directly touches them starts to sublime, this is how the fans tend to develop starting at those boulders.
    Please, mark them as interesting feature and with #boulders !
    Thank you for helping!
