Voir Yellowstone, Series 1 - Episode 3

An early autumn dusting of snow is a sign for elk to start moving down from the mountains to focus on finding food in the valleys below. Although the wolves are waiting for them, the male elk are distracted, they are fired up and ready to fight each other for the right to breed. Beavers get busy in a rush to repair dams and stock underwater larders before ice freezes their ponds. The white bark pine provides nuts to help fatten up grizzly bears and squirrels alike, as all the animals make preparations for another harsh winter season.
