Canyon Pack Bison Attacka photographic record of the attack
by Dan Hartman
Aug. 29, 2011The attack, which began the night before, continued Sunday morning. When the bison got to its feet, the wolves appeared to try for the hamstrings. As the wolves ripped at the bison's flanks, a bull moved in and several wolves backed off. Even with the agitated bull present, some wolves continued to attack. A second bull arrived to help out. When four bison surrounded the downed cow, all but the alpha male backed off. The bulls checked out the now dead cow. The bulls moved on, and the wolves returned. The pack began feeding, knowing grizzlies would probably soon arrive.
