These critters are Crabeater Seals. No one knows exactly why some of them are 25 miles up this dry, rocky valley. I'm not sure what the valley was like 5,000 years ago, maybe it had more lakes than there are now...lakes that weren't as frozen? Why some of them are 1,000 feet up the side of the valley is another mystery. Seeing them was one of the highlights of my trip in the Taylor Valley. It is crazy how humanlike their skeletons are; the similarities in the hands and feet is amazing. We all do come from the same life forms.
