Stumbled on this while backpacking out on the shoreline of Olympic National Park this weekend, deep in the wilderness. A large collection of bones: lots of ribs, vertebrae, maybe a skull? Also a big piece of soft tissue: Maybe a pectoral fin? It looked like a ball/socket on one end and phalanges on the other. All in all, hard to tell how long it had been there. But whatever it was, it’s big. Any guesses?
