Who wins in a fight between grizzly bear and an elephant?

A grizzly bear wouldn't dare mess with a bison bull or cow. When on the attack, a charging bison can and will gore a bear with its horns, not to mention crush the bear's ribs with his head. A bear can try to get at the neck, but all that thick fur will be in the way, and will come away with more injuries than he intended. A grizzly will steal and kill a bison calf, but only if the calf ventures far from his mother and from the safety of the herd.
