Kain, yes. That is a bear peel.
You can tell by the vertical teeth marks where they scraped the cambium layer.
As for size...they can very. Typically the trees are 10-12 inches through, but I have found trees peeled that were 3 & 4 feet through. Not all peels are at ground level either. Sometimes they start peeling 50 feet up.
They will peel fir, hemlock, spruce, cedar and even maple.
