Bark scraped from a fir trunk by the claws, exposing the inner bark, which shows tooth marks where an American Black Bear (Ursus americanus), scraped the inner bark (phloem) with its teeth in order to get nutrients after coming out of hibernation in spring, along the Iron Goat Trail near Stevens Pass, Mt. Baker – Snoqualmie National Forest, Cascade Mountains, Washington State, USA.
