This is a large grizzly boar(male). He caused quite a stir and traffic jam this day. We spent well over 4 hours keeping people away from the bear and directing traffic to keep the flow going. He wandered in between the river and the road looking for a dead bison that the rangers hauled away for safety reasons. The bison was where people could get close to it and this is dangerous because of bears like this guy. They turn very territorial when guarding their food and if people walk too close taking pictures, they may get mauled.
