Hailed as "the great nature writer of this generation" (Wall Street Journal), Robert Macfarlane is the celebrated author of books about the intersections of the human and the natural realms. In Underland, he delivers his masterpiece: an epic exploration of the Earth's underworlds as they exist in myth, literature, memory, and the land itself.

This essay by Thoreau first published in 1849, argues that individuals should not permit governments to overrule their consciences. It goes on to say that individuals have a duty to avoid allowing the government to make them the agents of injustice. The quote: "That government is best which governs least," sometimes attributed to Thomas Jefferson or Thomas Paine, actually was first found in this essay. Thoreaus' thoughts were motivated by his disgust with slavery and the Mexican-American War but they are still relevant and resonate today.

The Log from the Sea of Cortez is the exciting day-by-day account of Steinbeck's trip to the Gulf of California with biologist Ed Ricketts. Drawn from the longer Sea of Cortez, it is a wonderful combination of science, philosophy, and high-spirited adventure.

In 1793 William Smith, a canal digger, made a startling discovery that was to turn the fledgling science of the history of the earth - and a central plank of established Christian religion - on its head. He noticed that the rocks he was excavating were arranged in layers; more important, he could see quite clearly that the fossils found in one layer were very different from those found in another. And out of that realization came an epiphany.

Auckland Island is a godforsaken place in the middle of the Southern Ocean, 285 miles south of New Zealand. With year-round freezing rain and howling winds, it is one of the most forbidding places in the world. To be shipwrecked there means almost certain death. In 1864, Captain Thomas Musgrave and his crew of four aboard the schooner Grafton wreck on the southern end of the island. Utterly alone in a dense coastal forest, plagued by stinging blowflies and relentless rain, Captain Musgrave inspires his men to take action.

A random murder in a public park. An artist wracked by fantastical and haunting dreams. A police inspector confronting the depraved rites of a voodoo cult. Intrepid sailors pitted against a diabolical monstrosity risen from the bottom of the sea. And one man, doomed to understand that such things foretell madness and the end of mankind.

When a shattered kayak and camping gear are found on an uninhabited island, they reignite a mystery surrounding a shocking act of protest. Five months earlier, logger-turned-activist Grant Hadwin had plunged naked into a river in British Columbia's Queen Charlotte Islands, towing a chainsaw. When his night's work was done, a unique Sitka spruce, 165 feet tall and covered with luminous golden needles, teetered on its stump. Two days later it fell.

The legendary annihilation in 1883 of the volcano-island of Krakatoa - the name has since become a byword for a cataclysmic disaster - was followed by an immense tsunami that killed nearly 40,000 people. Beyond the purely physical horrors of an event that has only very recently been properly understood, the eruption changed the world in more ways than could possibly be imagined. Dust swirled round die planet for years, causing temperatures to plummet and sunsets to turn vivid with lurid and unsettling displays of light.

A thrilling, intellectual detective story that looks deep into the past to uncover who first settled the islands of the remote Pacific, where they came from, how they got there, and how we know.

Published in 1951, The Sea Around Us is one of the most remarkably successful books ever written about the natural world. This classic work remains as fresh today as when it first appeared. Carson's writing teems with stunning, memorable images - the newly formed Earth cooling beneath an endlessly overcast sky, the centuries of nonstop rain that created the oceans, giant squids battling sperm whales hundreds of fathoms below the surface, and incredibly powerful tides moving 100 billion tons of water daily in the Bay of Fundy.

Are history books giving us the whole story? Or is civilization far more complex and for older than we have been taught? Our school textbooks barely mention the 6,000-year-old Sumerian civilization, yet the latest archaeological findings at sites such as Jericho, and most recently, Gobekli Tepe in Turkey, have been dated to 10,000 BC. Civilization goes back at least another 10,000 years, if we are willing to believe what our ancestors themselves claimed.

Atlantic is a biography of a tremendous space that has been central to the ambitions of explorers, scientists, and warriors, and continues profoundly to affect our character, attitudes, and dreams. Spanning the ocean's story, from its geological origins to the age of exploration, from World War II battles to today's struggles with pollution and overfishing, Winchester's narrative is epic, intimate, and awe inspiring.

Masterfully tying together history, science, and human drama, The Lost Dinosaurs of Egypt is the gripping account of two of the 20th century's great expeditions of discovery. In 1911 a German paleontologist found the remains of four entirely new dinosaurs in the Egyptian desert, but in a single night, all of his work was destroyed. Eighty-nine years later, an American grad student leads an expedition to unearth Stromer's dinosaur graveyard, and in doing so, he stuns the scientific world.

Pulitzer Prize winner Wallace Stegner recounts the remarkable career of Major John Wesley Powell, the distinguished ethnologist and geologist who explored the Colorado River, the Grand Canyon, and the homeland of the Southwest Indian tribes. This classic work is a penetrating and insightful study of the Powell’s career, from the beginning of the Powell Survey, in which Powell and his men famously became the first to descend the Colorado River, to his eventual expulsion from the Geological Survey.

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.
