Award-winning nature writer Jack Turner directs his attention to one of America’s greatest natural treasures: the Greater Yellowstone Ecosystem. Comprised of two national parks, three national wildlife refuges, parts of six national forests, and eleven wilderness areas, Greater Yellowstone is a vast array of differing environments and geographies.In a series of essays, Turner explores this wonderland, venturing on twelve separate trips in all seasons using various modes of travel: hiking, climbing, skiing, canoeing lakes, floating rivers, and driving his way across the landscape. He treks down the Teton Range, picks up the Oregon Trail in the Red Desert, and floats the South Fork of the Snake River. Along the way he encounters a variety of wildlife: moose, elk, trout, and wolves.
