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

Alexander von Humboldt (1769-1859) was an intrepid explorer and the most famous scientist of his age. His restless life was packed with adventure and discovery, whether climbing the highest volcanoes in the world or racing through anthrax-infested Siberia. He came up with a radical vision of nature, that it was a complex and interconnected global force and did not exist for man's use alone. Ironically, his ideas have become so accepted and widespread that he has been nearly forgotten.

This is the Pulitzer Prize-winning biography of John Muir, the rugged individualist and passionate protector of the wild who saw that the encroachment of civilization into nature would threaten civilization itself.

Travelers often become enchanted with the first country that captures their hearts and gives them license to be free. For Wade Davis, it was Colombia. Now in a masterly new book, Davis tells of his travels on the mighty Magdalena, the river that made possible the nation. Along the way, he finds a people who have overcome years of conflict precisely because of their character, informed by an enduring spirit of place, and a deep love of a land that is home to the greatest ecological and geographical diversity on the planet.

Martín Prechtel revives a hitherto unknown Guatemalan Tzutujil Mayan tale of the beginnings of the world with a poetic retelling of the story. Prechtel authoritatively retells the powerful tale of the Tall Girl who weaves the world in a loom, her parents the Sun and the Moon who repudiate her suitors, and the mysterious man who disguises himself as a hummingbird to lure her away.

The Smoky God is a classic tale from the genre of hollow Earth or subterranean literature. A once-favorite tale of Amazing Stories publisher Ray Palmer, The Smoky God is the (purportedly true) tale of two Norwegian fishermen Jens and Olaf Jansen, who sailed their fishing vessel into the inner Earth in the year 1829. While in the center of the Earth, they find an entire society and meet a race and of advanced giants.

The Unlikely Peace at Cuchumaquic is both an epic story and a cry to the heart of humanity based on the author’s realization that human survival depends on keeping alive the seeds of our “original forgotten spiritual excellence.” Prechtel relates our current state of ecological crisis to the rapid disappearance of biodiversity, indigenous cultures, and shared human values. He demonstrates how real human culture is exterminated when real (not genetically modified) seeds are lost.

Penguin presents the unabridged, downloadable audiobook edition of Landmarks, a fascinating exploration of the relationship between language and landscapes by Robert Macfarlane, read by Roy McMillan.

Sometimes it seems we just can't get what we want. Circumstances thwart our best-laid plans. We struggle to live a heartfelt life. Worst of all, says Eldredge, the modern church mistakenly teaches its people to kill desire (calling it sin) and replace it with duty or obligation (calling it sanctification).

In 1855, Walt Whitman published, at his own expense, the first edition of Leaves of Grass, a visionary volume of 12 poems. Showing the influence of a uniquely American form of mysticism known as Transcendentalism, the writing is distinguished by an explosively innovative free-verse style and previously unmentionable subject matter. Exalting nature, celebrating the human body, and praising the senses and sexual love, this monumental work, now a classic of American poetry, was condemned as immoral upon publication.

Layering climate science, mythologies, nature writing, and personal experiences, Desert Notebooks offers a vital and necessary chronicle of our past and our present - perfect for fans of Robert Macfarlane and Elizabeth Rush - that’s unflinching, urgent, and yet timeless and profound.

Alone among the creatures of the world, man suffers a pang both bitter and sweet. It is an ache for the homecoming. The Greeks called it nostalgia. Post-modern man, homeless almost by definition, cannot understand nostalgia. If he is a progressive, dreaming of a utopia to come, he dismisses it contemptuously, eager to bury a past he despises. If he is a reactionary, he sentimentalizes it, dreaming of a lost golden age. In this profound reflection, Anthony Esolen explores the true meaning of nostalgia and its place in the human heart.
