This weekend my buddy and I went looking for black bear in Turnagain Pass; didn't see any black bear but say a phenomenal fight between two wolverines and a brown bear-wolverines won. At first we couldn't tell if it was two cubs playing, but they weren't friendly and we realized they were actually fighting; a boar fighting a cub; or a sow trying to run off its cubs. It was just a mess of fur and they were rolling hundreds of yards before they got up and re-convened and we got a better look. When they broke up we saw the tail on one of the wolverines and we realized it was two big wolverines fighting a brown bear. Fight ended when both wolverines rolled the bear down the hill and it split-couldn't tell if it was a young sow or boar, but it wasn't big.
Never did see a black bear, saw one fox though.
BTW, snowmachiners have trashed Turnagain Pass, see my comments in the snowmachine forum.
