Yellowstone National Park was once home to an abundance of wild wolves - but park rangers killed the last of their kind in the 1920s. Decades later, the rangers brought them back, with the first wolves arriving from Canada in 1995. This is the incredible true story of one of those wolves.

Jack Olsen's true account, traces the causes of the tragic night in August 1967 when two separate and unrelated campers, a distance apart, were savagely mangled and killed by enraged bears.

Imagine raising an orphaned bear cub, carefully reintroducing her to the wild, then being welcomed back, almost daily, to observe her wild world for more than 17 years. Imagine visiting her in her feeding spots, watching her with her mates and her young, peering into her den, and, over time, observing the lives of all the other wild bears in her territory and surrounding ones. That is what happened to Ben Kilham.

The grizzly is one of North America's few remaining large predators. Their range is diminished, but they're spreading across the West again. Descending into valleys where once they were king, bears find the landscape they'd known for eons utterly changed by the new most dominant animal: humans. In searing detail, award-winning writer, Montana rancher, and conservationist Bryce Andrews tells us about one such grizzly. Millie is a typical mother: strong, cunning, fiercely protective of her cubs. But raising those cubs becomes ever harder as the climate warms and people crowd the valleys.

Even among iconic frontiersmen like John C. Fremont, Kit Carson, and Jedediah Smith, Jim Bridger stands out. A mountain man of the American West, straddling the fur trade era and the age of exploration, he lived the life legends are made of. Here, in a biography that finally gives this outsize character his due, Jerry Enzler takes this frontiersman's full measure for the first time—and tells a story that would do Jim Bridger proud.

Before men ruled the earth, there were wolves. Once abundant in North America, these majestic creatures were hunted to near extinction in the lower 48 states by the 1920s. But in recent decades, conservationists have brought wolves back to the Rockies, igniting a battle over the very soul of the West. With novelistic detail, Nate Blakeslee tells the gripping story of one of these wolves, O-Six, a charismatic alpha female named for the year of her birth.

On the Alaska Peninsula, where exceptional landscapes are commonplace, a small river attracts attention far beyond its scale. Each year, from summer to early fall, brown bears and salmon gather at Brooks River to create one of North America's greatest wildlife spectacles. As the salmon leap from the cascade, dozens of bears are there to catch them, and thousands of people come to watch in person or on the National Park Service's popular Brooks Falls Bearcam. The Bears of Brooks Falls tells the story of this region and the bears that made it famous.

In 1804, John Colter set out with Meriwether Lewis and William Clark on the first US expedition to traverse the North American continent. During the 28-month ordeal, Colter served as a hunter and scout, and honed his survival skills on the western frontier. But when the journey was over, Colter stayed behind. He spent two more years trekking alone through dangerous and unfamiliar territory, charting some of the West's most treasured landmarks.

When Zach Connors and his pa left their Kentucky homestead in the summer of 1824 to see the Rocky Mountains, he didn't realize he would never see his childhood home again or that he would find love, friendship, fame, and a new home in this wild and harsh wilderness. After a grizzly kills his pa, Zach struggles to survive a cold and brutal winter alone. After killing a rouge grizzly and fighting hostile Indians on his own, he becomes known as Grizzly Killer and is respected throughout the West. Along with his dog, Jimbo, whom the Indians call the Great Medicine Dog, he finds Running Wolf, an injured Ute warrior, and together they fight off a hostile war party. They rescue two Shoshone sisters from the brutality of a French trapper and take them as wives.

The Earth teems with sights and textures, sounds and vibrations, smells and tastes, electric and magnetic fields. But every kind of animal, including humans, is enclosed within its own unique sensory bubble, perceiving but a tiny sliver of our immense world. In An Immense World, Ed Yong coaxes us beyond the confines of our own senses, allowing us to perceive the skeins of scent, waves of electromagnetism, and pulses of pressure that surround us.

Empire of Shadows is the epic story of the conquest of Yellowstone, a landscape uninhabited, inaccessible, and shrouded in myth in the aftermath of the Civil War. In a radical reinterpretation of the 19th century West, George Black casts Yellowstone's creation as the culmination of three interwoven strands of history.

In 1908, near Folsom, New Mexico, a cowboy discovered the remains of a herd of extinct giant bison. By examining flint points embedded in the bones, archeologists later determined that a band of humans had killed and butchered the animals 12,450 years ago. This discovery vastly expanded America's known human history but also revealed the long-standing danger Homo sapiens presented to the continent's evolutionary richness. Distinguished scholar Dan Flores's ambitious history chronicles the epoch in which humans and animals have coexisted in the "wild new world" of North America.

In Eager, environmental journalist Ben Goldfarb reveals that our modern idea of what a healthy landscape looks like and how it functions is wrong, distorted by the fur trade that once trapped out millions of beavers from North America's lakes and rivers. The consequences of losing beavers were profound: streams eroded, wetlands dried up, and species from salmon to swans lost vital habitat. Today, a growing coalition of "Beaver Believers" recognizes that ecosystems with beavers are far healthier, for humans and non-humans alike, than those without them.

Sy Montgomery's popular 2011 Orion magazine piece, "Deep Intellect", about her friendship with a sensitive, sweet-natured octopus named Athena and the grief she felt at her death, went viral, indicating the widespread fascination with these mysterious, almost alien-like creatures. Since then Sy has practiced true immersion journalism, from New England aquarium tanks to the reefs of French Polynesia and the Gulf of Mexico, pursuing these wild, solitary shape-shifters.

America's Great Plains once possessed one of the grandest wildlife spectacles of the world, equaled only by such places as the Serengeti, the Masai Mara, or the veld of South Africa. Pronghorn antelope, gray wolves, bison, coyotes, wild horses, and grizzly bears: less than 200 years ago these creatures existed in such abundance that John James Audubon was moved to write "it is impossible to describe or even conceive the vast multitudes of these animals".

Coyote America is both an environmental and a deep natural history of the coyote. It traces both the five-million-year-long biological story of an animal that has become the "wolf" in our backyards and its cultural evolution from a preeminent spot in Native American religions to the hapless foil of the Road Runner. A deeply American tale, the story of the coyote in the American West and beyond is a sort of Manifest Destiny in reverse.

For millennia, lions, tigers, and their man-eating kin have kept our dark, scary forests dark and scary, and their predatory majesty has been the stuff of folklore. But by the year 2150 big predators may only exist on the other side of glass barriers and chain-link fences. Their gradual disappearance is changing the very nature of our existence. We no longer occupy an intermediate position on the food chain; instead we survey it invulnerably from above - so far above that we are in danger of forgetting that we even belong to an ecosystem.

A riveting history of America's most beautiful natural resources, The Quiet World documents the heroic fight waged by the U.S. federal government from 1879 to 1960 to save wild Alaska - ;Mount McKinley, the Tongass and Chugach national forests, Gates of the Arctic, Glacier Bay, Lake Clark, and the Coastal Plain of the Beaufort Sea, among other treasured landscapes - from the extraction industries.

In this groundbreaking epic biography, Douglas Brinkley draws on never-before-published materials to examine the life and achievements of our "naturalist president." By setting aside more than 230 million acres of wild America for posterity between 1901 and 1909, Theodore Roosevelt made conservation a universal endeavor. This crusade for the American wilderness was perhaps the greatest U.S. presidential initiative between the Civil War and World War I.

When 25-year-old Harry Walker was killed by a bear in Yellowstone Park in 1972, the civil trial prompted by his death became a proxy for bigger questions about American wilderness management that had been boiling for a century. At immediate issue was whether the Park Service should have done more to keep bears away from humans, but what was revealed as the trial unfolded was just how fruitless our efforts to regulate nature in the parks had always been.

Late one June night in 2011, a large animal collided with an SUV cruising down a Connecticut parkway. The creature appeared as something out of New England's forgotten past. Beside the road lay a 140-pound mountain lion. Speculations ran wild, the wildest of which figured him a ghostly survivor from a bygone century when lions last roamed the eastern United States. But a more fantastic scenario of facts soon unfolded.

A major new exploration of the economics of animal exploitation and a practical road map for how we can use the marketplace to promote the welfare of all living creatures from the renowned animal-rights advocate Wayne Pacelle, president and CEO of the Humane Society of the United States and New York Times best-selling author of The Bond.

In the last three decades of the 19th century, an American buffalo herd once numbering 30 million animals was reduced to 23. It was the era of Manifest Destiny, a gilded age that viewed the West as nothing more than a treasure chest of resources to be dug up or shot down. Supporting hide hunters was the US Army, which considered the eradication of the buffalo essential to victory in its ongoing war on Native Americans.

The bald eagle is regal but fearless, a bird you’re not inclined to argue with. For centuries, Americans have celebrated it as “majestic” and “noble,” yet savaged the living bird behind their national symbol as a malicious predator of livestock and, falsely, a snatcher of babies.

In a powerful blend of history and contemporary reporting, New York Times reporter David Philipps traces the rich history of wild horses in America: their introduction by the Spanish conquistadors, their role in the epic battles between Native Americans and settlers, their vital place in American self-mythology. He travels through some of the most remote parts of the American West, known as Wild Horse Country, to investigate the wild horse's current dilemma, caught between the clashing ideals of ranchers, scientists, and more.

Half of all species could disappear by the end of the century, and scientists now concede that most of America’s endangered animals will survive only if conservationists keep rigging the world around them in their favor. So Jon Mooallem ventures into the field, often taking his daughter with him, to move beyond childlike fascination and make those creatures feel more real. Wild Ones is a tour through our environmental moment and the eccentric cultural history of people and wild animals in America that inflects it.

That the dog evolved from the wolf is an accepted fact of evolution and history, but the question of how wolf became dog has remained a mystery, obscured by myth and legend. How the Dog Became the Dog posits that dog was an evolutionary inevitability in the nature of the wolf and its human soul mate. The natural temperament and social structure of humans and wolves are so similar that as soon as they met on the trail they recognized themselves in each other.

This audiobook explores the deep past and examines the latest knowledge on bison anatomy and physiology, how bison responded to climate change (especially drought), and early bison hunters and pre-contact trade. It also focuses on the era of European contact, in particular the arrival of the horse, and some of the first known instances of over-hunting. By the 19th century, bison reached a "tipping point" as a result of new tanning practices, an early attempt at protective legislation, and ventures to introducing cattle as a replacement stock.

Richard Louv's landmark book, Last Child in the Woods, inspired an international movement to connect children and nature. Now Louv redefines the future of human-animal coexistence. Our Wild Calling explores these powerful and mysterious bonds and how they can transform our mental, physical, and spiritual lives, serve as an antidote to the growing epidemic of human loneliness, and help us tap into the empathy required to preserve life on Earth.
