These bowhunters were floating down an Alaskan river when they happened upon a group of three grizzly bear cubs. The mood of the hunters instantly changed when they saw the bears, because cubs are never far from their mother.
Sure enough, the mother grizzly spotted the hunters and immediately started to charge them.
The reason we are watching this footage today is because of the hunting guide who instinctively pulled out his revolver and fired at the water in front of the charging bear. Never get between a mother grizzly and her cubs!
