Yellowstone, the oldest National Park on earth: famous for its diverse wildlife and a massive magma chamber in the depths that characterizes its distinctive landscapes. The National Park in the western United States reminds us of the importance of protected areas - and at the same time impressively demonstrates that wilderness knows no boundaries. Bison and wolves, almost extinct and lost, have returned to this area. But wild animals want to migrate, further north than ever before, when the earth's climate changes. Yellowstone offers ideas. For a year, a team traveled to the Rocky Mountains and accompanied rangers, explorers and adventurers in their incredible daily lives, which are otherwise hidden from visitors. It is an excursion to one of the most beautiful and wildest areas on earth between deep snow and Indian summer.
