No place on Earth is like Yellowstone in winter.  This world of fire and ice has thousands of boiling hot springs, geysers, and bubbling mud pots. In Yellowstone every animal struggles to find food and stay alive against an onslaught of heavy snows, polar temperatures, and ferocious predators. Beavers and grizzly bears retreat under cover from the endless blizzard, while the wolves, red fox, and river otters face winter head on.

In summer Yellowstone transforms into a wildlife paradise, with a cruel dark side. From torrential floods in spring to burning sun in August, summer presents new challenges and opportunities. Animal dramas ensue: predators on the prowl and parents protecting offspring, bears fighting wolves, and trout running gauntlets of river otters and osprey. Even the hummingbird goes to battle, fighting in mid-air to protect a territory of wildflowers.
