Quoting from John Muir's diaries， Kathryn Lasky tells the inspiring tale of one of America's most dedicated environmentalists， aided by Stan Fellows's evocative， dramatic acrylic paintings. From the meadows of Scotland to the farms of Wisconsin， from the swamps of Florida to the Alaskan tundra， John Muir loved the land. Born in 1838， he was a writer， a scholar， an inventor， a shepherd， a farmer， and an explorer， but above all， he was a naturalist. John Muir was particularly devoted to the high cliffs， waterfalls， and ancient giant sequoia trees that， through his careful influence， were set aside as one of the first national parks in America - Yosemite. Here is the life story of the man who， moved by a commitment to wilderness everywhere， founded the Sierra Club in 1892， a conservation group that carries on his crucial work to this day.
