Changes on Earth
In this Stunning New Three-Part Series airing Wednesdays through July 5th at 9pm/ET
Host & Smithsonian National Museum of Natural History Director Dr. Kirk Johnson Takes You Behind the Scenes at the Nation’s First National Park. You’ll be Amazed by the Intimate Footage of Animals Struggling to Adapt to Extreme Weather Conditions in the Park’s Brutal Spring Season.
Great Yellowstone Thaw gives viewers an appreciation and insight into the amazing adaptability of animals in an often brutal environment, showcasing the extraordinary survival instincts the park’s natural species possess. From winter to summer, Yellowstone’s temperature typically swings 140 degrees. Filmed over several intense months, from deep winter to early summer, the series intercuts the stories of several different animal families—including wolves, bison, grizzlies, beavers and great gray owls. It follows the animals in the Yellowstone ecosystem as they emerge from winter’s cold and adapt to an early spring thaw, before encountering the soaring summer temperatures.
Johnson and a team of Yellowstone experts explore how these animals fend off floods, starvation, and fires, as well as the area’s extreme evolution from cold to heat during the spring season. Great Yellowstone Thaw is part of “PBS Summer of Adventure” – taking viewers and their families on an adventure around the world this season. The series is a co-production between PBS, BBC and BBC Worldwide North America.
