Beaver-gnawed wood and broken wood in a tree trunk

At right are marks made by beaver teeth when this poplar tree was gnawed in an effort to cut down and topple it. Eventually the structurally weakened tree broke from its base (which became a stump) and fell over, producing the broken fibrous texture in the core of the trunk, seen at left. Seen close to the shore of the Elbow River in central Calgary, Alberta, western Canada.
