NOVA: Life's Rocky Start

Twelve talented young mountaineers, five geologists from the University of Lausanne and four mountain guides take an unprecedented risk in Patagonia. Trained by the great climbers Ralf Weber, Ueli Steck, Denis Burdet and David Fasel, the young people are collecting rock samples from the granite walls of the Paine Towers, which are up to 1000 meters high, on behalf of science. The challenges are enormous: Climbing a big wall at the highest level of difficulty, cloudy weather, relentless wind that tears at material and nerves - and an urgency that also pushes the group to their emotional limits. "Flying High" not only documents an extraordinary undertaking, but also shows up close what happens when something happens that can happen after every meter of altitude climbed: a fall.

The epic story of the life of a volcano, capable of both causing the extinction of all things and helping the evolution of species, over 60 million years.

Sparkling diamonds. Exquisite emeralds. Brilliant rubies. Shimmering pearls. For centuries, these precious gems have captured humankind, leading men and women to give up fortunes - even their lives - to possess them. Join National Geographic on a journey around the globe to discover the origins of these most coveted gems. You'll see astonishing amounts of earth mined to uncover rubies in Thailand or emeralds in Colombia. You'll meet a Tennessee businessman who cultivates freshwater pearls and a California chemist who 'grows' rubies nearly identical to nature's stunning creations. And you'll witness rarely, if ever before, filmed sales of uncut diamonds - deals worth thousands of dollars sealed only with a handshake and a Hebrew phrase. Unlock a treasure chest filled with a wealth of information and the dazzling beauty of Splendid Stones.

Ring of Fire is about the immense natural force of the great circle of volcanoes and seismic activity that rings the Pacific Ocean and the varied people and cultures who coexist with them. Spectacular volcanic eruptions are featured, including Mount St. Helens, Navidad in Chile, Sakurajima in Japan, and Mount Merapi in Indonesia.

In this retrospective tribute, acclaimed filmmaker Jean Walkinshaw hails the 100th anniversary of Mount Rainier National Park in Washington by talking to those who know it best: the scientists, naturalists, mountain climbers and artists whose lives have been touched by the peak's far-reaching shadow. The result is a harmonious blend of archival material and high-definition footage celebrating an icon of the Pacific Northwest.

In this fascinating sequel to "Is Genesis History?", watch a team of scientists discover new evidence for the global Flood. By the time the journey is over, you'll understand exactly how modern science connects to the book of Genesis.

Face of the Earth explores the origin of our planet's outer layer, the why-and-how of its mobility. Through the use of well-designed diagrams, the earth's cyclical activity is clearly explained. Some unusual footage on volcanoes gives added punch to an already absorbing subject.

An epic cinematic and musical collaboration between SHERPA filmmaker Jennifer Peedom and the Australian Chamber Orchestra, that explores humankind's fascination with high places.

The fascinating landscape formations of Iceland in the North Atlantic bear witness to the beauty and primal power of nature. They were created through the interaction of powerful volcanic, geological and biological processes that have been changing the face of the earth for billions of years. This is what the Earth might have looked like four billion years ago. Iceland is the realm of ice and fire. Nowhere else is there such a high density of volcanoes. The landscapes, which are continually reshaped by eruptions, make the island a natural laboratory full of clues about the formation and development of the earth. The documentary follows a group of scientists through the most active areas of Iceland, along a mountain range that has emerged from the ocean. On the slopes of the volcanoes, in the fog of the fumaroles and on streams and rivers, the three researchers explore how the first forms of life populated the earth's surface and in what evolutionary steps they took over the earth.

The Channeled Scablands in Washington state defied conventional explanations for their formation for decades. Little by little evidence mounted for an old theory that was rejected by the scientific establishment. It involved glaciers, volcanoes, a relatively minor river and a prodigious amount of water. Originally aired as an episide of NOVA.

NGC goes inside one of the greatest natural marvels on the planet - a giant crystal cave described as Superman's fortress, with magnificent crystals up to 36 feet long and weighing 55 tons. A team of experts venture into the cavern, enduring scorching-hot temperatures that could kill a human after just 15 minutes of exposure. They'll push the boundaries of physical limitation to explore a crevasse that could lead to another - and perhaps more spectacular - crystal cave.

Millions of years scroll by in 10 minutes, illustrated by ingenious designers: this is the geological history of Canada.

A worldwide scientific investigation on tsunamis. Thanks to exclusive access in Palu, Indonesia, follow the UN’s hand-picked scientific team of "tsunami hunters". Where do they strike? How do they submerge us? What can we do to survive them?
