Bears possess enormous strength, regardless of species or size. The strength of a bear is difficult to measure, but observations of bears moving rocks, carrying animal carcasses, removing large logs from the side of a cabin, and digging cavernous holes are all indicative of enormous power. No animal of equal size is as powerful. A bear may kill a moose, elk, or deer by a single blow to the neck with a powerful foreleg, then lift the carcass in its mouth and carry it for great distances.
