Dark radially converging dendritic patterns are visible in MOC images of some portions of the spring polar cap, these have been termed " spiders" by the MOC team. In this model, these patterns represent channels formed by subslab channelized flow of the sublimation gas toward the vents. Increasingly large particles could become entrained closer to the vent.
