Gore and Bryant go towards the second cairn while the rest of the group retrieve the boat. Goodsir and the others return to the boat and find it overturned and their supplies scattered. Des Voeux thinks a bear did it, and Goodsir worries there might be more than one. Gore's group is forced inside their tents when they are bombarded by large hail. While they are huddled in their tents, they hear a creature roar. Bryant tells the others, he and Gore were being tracked by a bear. He tells everyone to grab a rifle and when he sees a shadow, shoots at it, hitting a Shaman. Goodsir is called over and finds Lady Silence crying over the wounded Shaman.
