Threatening with big attachment

Big Black Bear threatened me cruising up river from beach one spring day of May in the Arctic Yukon. The bear was holding this caribou carcass there. It might be killed by this bear or die accidentally when it was crossing river as part of spring migration. It was too late to know the drama what happened between them. The carcass was eaten most of it already but still had some meat to eat even this bear seemed full. I wasn't sure when this bear hunted or found this caribou, how long this guy took to eat big amount of meat, almost one caribou. The bear had stayed and attached this dead caribou during I was observing in spite of wolf was hiding and aiming meat in the bush behind of the bear. Unfortunately, the wolf couldn't be taken pictures like a ghost.
