When a wolf swam after a mighty buck in the depths of a northern Alberta lake, David Smith was there to capture the rare sight, frame by frame.”The stag jumped out of the bush and the wolf jumped right in after it and tried to swim and bite it,” Smith said. “This probably went on for a minute and then the wolf turned around.”He probably realized it wasn’t going to have too much of an opportunity to kill this animal in the middle of the lake.”
