There is a closer up photo of the tip of the hut point peninsula. Since 2000 the ice hasn’t melted in front of town. It’s thins out and becomes unsafe to travel on but hasn’t broken up in many years. That historically is not the norm. If you look carefully at the photo you can see the extent of previous breakups of the ice shelf. The ice runway is on sea ice that breaks up, Willy is on the iceshelf on snow pack, Pegasus is on hard ice.
Look here at the the radar image. You can see it even better.
