America's national parks spring from an idea as radical as the Declaration of Independence: that the nation's most magnificent and sacred places should be preserved, not for royalty or the rich, but for everyone. In this evocative narrative, Ken Burns and Dayton Duncan delve into the history of the park idea.

Part of John Muir's appeal to modern audiences is that he not only explored the American West and wrote about its beauties but also fought for their preservation. His successes dot the landscape and are evident in all the natural features that bear his name: forests, lakes, trails, and glaciers. Here collected are some of Muir's finest wilderness essays, ranging in subject matter from Alaska to Yellowstone, from Oregon to the High Sierra.

The real stories behind the scenery of America’s national parks. For 12 years, Andrea Lankford lived in the biggest, most impressive national parks in the world, working a job she loved. She chaperoned baby sea turtles on their journey to sea. She pursued bad guys on her galloping patrol horse. She jumped into rescue helicopters bound for the heart of the Grand Canyon. She won arguments with bears. She slept with a few too many rattlesnakes. Hell yeah, it was the best job in the world! Fortunately, Andrea survived it.

The pioneering advocate of wilderness preservation, John Muir (1838-1914) was influential in the creation of many national parks.

It was June of 1869 when John Muir reluctantly accepted a job herding sheep from the central valley of California to the headwaters of the Merced and Tuolumne Rivers, high into the Sierra Nevadas and deep into the Yosemite region. He felt ill equipped for the work, and yet the opportunity thrilled his adventurous spirit. With a notebook tied to his belt, he set out for a summer he would never forget. My First Summer in the Sierra is Muir’s classic account of that extraordinary journey.

"Stickeen.... pushed his head past my shoulders, looked down and across, then looked me in the face and began to mutter and whine; saying as plainly as if speaking with words, "Surely, you are not going into that awful place. "As the darkness of a freezing night approaches, an experienced American naturalist and a dog are trapped on an Alaskan Glacier. This is a true story, written by one of the United States' most famous naturalists and explorers.

I had long been looking from the wildwoods and gardens of the Northern States to those of the warm South, and at last, all draw-backs overcome, I set forth [from Indianapolis] on the first day of September, 1867, joyful and free, on a thousand-mile walk to the Gulf of Mexico. Crossing the Ohio at Louisville, I steered through the big city by compass without speaking a word to any one.

John Muir (1838 -1914) was an influential Scottish-American naturalist, author, environmental philosopher, and early advocate for the preservation of wilderness areas in the United States. In the late 1800s, Muir made several trips to the relatively unexplored territory of Alaska. Travels in Alaska, originally published in 1915, describes the beauty of the Alaskan wilderness and its inhabitants as observed during his travels between 1879 and 1890. In poetic prose, he describes the area’s magnificent glaciers and its animals like bears, bald eagles, wolves and whales.

"I am hopelessly and forever a mountaineer," John Muir wrote. "Civilization and fever and all the morbidness that has been hooted at me has not dimmed my glacial eye, and I care to live only to entice people to look at Nature's loveliness. My own special self is nothing". In Donald Worster's magisterial biography, John Muir's "special self" is fully explored as is his extraordinary ability, then and now, to get others to see the sacred beauty of the natural world.

In the spring of 1804, at the behest of President oThomas Jefferson, a party of explorers called the Corps of Discovery crossed the Mississippi River and started up the Missouri, heading west into the newly acquired Louisiana Territory.

When Conor Knighton set off to explore America's "best idea", he worried the whole thing could end up being his worst idea. A broken engagement and a broken heart had left him longing for a change of scenery, but the plan he'd cooked up in response had gone a bit overboard in that department: Over the course of a single year, Knighton would visit every national park in the country, from Acadia to Zion.

Perhaps no American president is more associated with nature and wildlife than Theodore Roosevelt, a prodigious hunter and adventurer and an ardent conservationist. We think of Roosevelt as an original, yet in The Naturalist, Darrin Lunde shows how from his earliest days Roosevelt actively modeled himself in the proud tradition of museum naturalists - the men who pioneered a key branch of American biology through their desire to collect animal specimens and develop a taxonomy of the natural world.

How do trees live? Do they feel pain or have awareness of their surroundings? Research is now suggesting trees are capable of much more than we have ever known. In The Hidden Life of Trees, forester Peter Wohlleben puts groundbreaking scientific discoveries into a language everyone can relate to.

The Appalachian Trail trail stretches from Georgia to Maine and covers some of the most breathtaking terrain in America - majestic mountains, silent forests, sparking lakes. If you’re going to take a hike, it’s probably the place to go. And Bill Bryson is surely the most entertaing guide you’ll find. He introduces us to the history and ecology of the trail and to some of the other hardy (or just foolhardy) folks he meets along the way - and a couple of bears. Already a classic, A Walk in the Woods will make you long for the great outdoors (or at least a comfortable chair to sit and read in).

A humorous and rousing set of literal and figurative sojourns as well as a mission statement about comprehending, protecting, and truly experiencing the outdoors, fueled by three journeys undertaken by actor, humorist, and New York Times best-selling author Nick Offerman

For two years, Scots-born John Muir lived in a small cabin along the Yosemite creek, observing the valley's natural beauty and reading Emerson under the stars. The experience forged a lifelong affinity with the site, which would result in its establishment as a national park in 1890. Originally written as a guidebook to the park, The Yosemite describes every aspect of wildlife and landscape that one might encounter there.

Spanning more than 84 million acres, the national parks have something for everyone. Whether you want to traverse rocky mountain cliffs, see majestic wildlife like black bears and buffalo, or walk the rims of active volcanoes, any outdoor adventure is possible. You just have to know where to go. Which is exactly where this book comes in handy.

Many Americans remember a family road trip to visit one of our 63 national parks. Why did Americans start preserving these sites of natural and historic interest? How were these parks selected, and what steps did conservationists, activists, philanthropists, politicians, and others take to protect millions of acres against the booming developments of an expanding nation? An award-winning writer, researcher, and American Studies scholar, Dr. Megan Kate Nelson tackles these questions as she takes you on a marvelous journey through some of the most beautiful places on Earth.
