A biography of John Muir, naturalist and founder of the Sierra Club, whose travels, speeches and writings led directly to the creation of the Yosemite National Park in 1890 and other national parks that followed. 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 the first national park 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.
