Established in 1872, Yellowstone is America s first national park and a global destination. To this day, Yellowstone remains one of the world s most popular destinations. The Greater Yellowstone Ecosystem spans almost 3,500 miles, and extends into parts of Montana, Wyoming, and Idaho, also making it one of the largest national parks in the United States. Grand Teton National Park, home of the majestic mountain range, was preserved as a national park in 1929. Since then, interest in the neighbour parks has grown dramatically, and today more than seven million people visit the two parks annually. This book offers stunning photographs of every corner of the 2.2 million acres that make up these parks, including such treasures as Lake Yellowstone, the Grand Canyon of the Yellowstone River, Old Faithful, and the Snake and Yellowstone Rivers, as well as the wide plains of the Lamar Valley North America s equivalent of the African Serengeti. Yellowstone sits at the heart of the only bioregion in the Lower 48 states that still contains all of the free-roaming mammals that were present before the arrival of Europeans on the North American continent: wolves, elk, bison, grizzlies, and countless species of birds. For years, Thomas D. Mangelsen has been asked why he had never devoted a book singularly to Yellowstone and his reply was always, I am waiting for the right moment, and I want a collection worthy of Yellowstone s celebration. With Seasons of Yellowstone, the moment has arrived.
