Yellowstone鈥檚 top predator - the wolf - has dominated Yellowstone over the winter, but is far less visible in summer. Wolves prefer to stay close to well hidden dens to protect their pups from rival packs. This pack seem prepared to allow their young a brief foray to experience the world beyond their den. Even in Yellowstone it is extremely rare to see wolf pups like this, playing in the open on the bank of the river. Before long they are summoned back into the forest by the pack and it'll be winter before they are regularly seen again.
