BBC natural history documentary sees Kate Humble and Patrick Aryee witness the changing seasons at Yellowstone National Park. Larger than some American states, Yellowstone National Park is one of the world’s last and most spectacular wildernesses - a global icon of natural beauty. It is also home to some of the richest wildlife beyond the plains of Africa. Against its vast and majestic landscapes, full of lush meadows, deep forests and violent hot springs, this landmark series follows the intertwining stories of Yellowstone’s iconic inhabitants: the grey wolf, the grizzly bear and the herds of antelope and buffalo. In a land of beauty and peril, the dramatic lives and fortunes of these animals are inexorably bound together. Intimate and emotional, epic and engaging, Yellowstone reveals the grandeur of this unique place as its animals struggle to survive over the course of three vividly changing seasons.
