  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. Look at examples here http://blog.planetfour.org/
  Mark them with interesting features, please!
