Book excerpt: 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. From the treacherous mountains in the dead of winter, to lush river valleys in the height of fishing season, his words and steps trace one of the most American of experiences---exploring the West. Turner, who has lived in Grand Teton for three decades, designates Greater Yellowstone as ground zero for the country's conflict between preservation and development. At a time when the battle to preserve a wild and natural environment is relentless, his accounts of the areas conflicts with alien species, logging, real estate, oil, and gas development are alarming. A mixture of adventure, nostalgia, and Americana, Turner's rare experiences and evocative writing transform the sights and sounds of Greater Yellowstone into an intimate narrative of travel through America's most beloved lands. Praise for Teewinot: "Bursting with a sense of place...a rewarding reading experience replete with ravishing observations of nature." - Publishers Weekly "...a measured luxuriance in the landscape, a love song to the natural history of a place...Turner's writing is muscular, never swaggering, and almost lyrical, summoning a Teton Range in its rightful, sublime austerity." - Kirkus Reviews "Teewinot is a rare book. The wonderful accounts of mountaineering serve as armature not only for Turner's meditative reverence for the Grand Tetons and his often evocative prose but also for an uncommon density of knowledge of place..." - Peter Matthiessen, author of Tigers in the Snow "This is, simply stated, a wonderful and utterly engaging book." - Jim Harrison, author of Dalva and The Road Home "Each place must find its muse. The Tetons have found theirs and his name is Jack Turner." - Terry Tempest Williams, author of Coyote's Canyon
