At last, there is hope. They have finally reached the pack-ice that forms the polar icecap. It’s the ultimate hunting habitat for polar bears. The icecap stretches all the way to the North Pole. Seals are found wherever it meets the sea. It’s been a long journey. There are a hundred miles from Svalbard and 150 miles from the den-sites where they were born. For now, she can relax, having fulfilled her mission. It’s the perfect spot to spend the few months left of summer.
It is four months since Svalbard was surrounded by sea ice. It could be another two before it freezes again. Guided by her sense of smell, the mother discovers what's left of the stranded 1 whale, but it looks like the remains 2 have been stripped clean by bears. The massive backbone 3 says it all. There is not a scrap 4 to be found. This was their last hope. With the carcass gone, the bears search the shore for scraps 5. All the remains are sun-bleached bones. There is little nutrition here, but at least the cub 6 has found something to chew on.
