In the late 19th century, demand for fur was in sharp decline. This could have spelled economic disaster for the venerable Hudson's Bay Company. But an idea emerged in political and business circles in Ottawa and Montreal to connect the disparate British colonies into a single entity that would stretch from the Atlantic to the Pacific. With over 3,000 kilometers of track, much of it driven through wildly inhospitable terrain, the CPR would be the longest railroad in the world and the most difficult to build. Its construction was the defining event of its era.

"Dr. Livingstone, I presume?" So goes the signature introduction of New York Herald star journalist Henry Morton Stanley to renowned explorer Dr. David Livingstone, who had been missing for six years in the wilds of Africa. Into Africa ushers us into the meeting of these remarkable men. In 1866, when Livingstone journeyed into the heart of the African continent in search of the Nile's source, the land was rough, unknown to Europeans, and inhabited by man-eating tribes.

Traverspine is not a place you will find on most maps. A century ago, it stood near the foothills of the remote Mealy Mountains in central Labrador. Today it is an abandoned ghost town, almost all trace of it swallowed up by dark spruce woods that cloak millions of acres. In the early 1900s, this isolated little settlement was the scene of an extraordinary haunting by large creatures none could identify. Strange tracks were found in the woods. Unearthly cries were heard in the night. Sled dogs went missing.

When gold was discovered at Sutter's Mill on the American River, it completely transformed the territory of California. Hundreds of thousands of people sped to California by any means possible, and small cities sprung up to service their needs as they sought the precious metal. By 1850, California had become a state; it had also become a symbol of where the nation was going.

In August 1897, the young Belgian commandant Adrien de Gerlache set sail for a three-year expedition aboard the good ship Belgica with dreams of glory. His destination was the uncharted end of the earth: the icy continent of Antarctica. But de Gerlache’s plans to be first to the magnetic South Pole would swiftly go awry. After a series of costly setbacks, the commandant faced two bad options: turn back in defeat and spare his men the devastating Antarctic winter, or recklessly chase fame by sailing deeper into the freezing waters.

In July 1881, Lt. A. W. Greely and his crew of 24 scientists and explorers were bound for the last region unmarked on global maps. Their goal: Farthest North. What would follow was one of the most extraordinary and terrible voyages ever made. Greely and his men confronted every possible challenge - vicious wolves, sub-zero temperatures, and months of total darkness - as they set about exploring one of the most remote, unrelenting environments on the planet. In May 1882, they broke the 300-year-old record, and returned to camp to eagerly await the resupply ship. Only nothing came.

In the late nineteenth century, people were obsessed by one of the last unmapped areas of the globe: The North Pole. No one knew what existed beyond the fortress of ice rimming the northern oceans. On July 8, 1879, the USS Jeannette set sail from San Francisco to cheering crowds in the grip of "Arctic Fever." The ship sailed into uncharted seas, but soon was trapped in pack ice. Two years into the harrowing voyage, the hull was breached. Amid the rush of water and the shrieks of breaking wooden boards, the crew abandoned the ship.

Dolly Faulkner has many heart-stopping moments of terror and anxiety, living much of the time truly alone in the Alaskan wilderness. But she is not lonely, as the awesome space and beauty of the mountains fill her with appreciation of all things of nature. Dolly Faulkner came to Alaska as a young woman with the dream of living in the wilderness. Forty Years in the Wilderness is a true reality of carving out a homestead in the Kilbuck Mountains near a minor hotsprings that the regional Native corporation is now trying to claim.

In 1973, Norma Cobb, her husband Lester, and their five children pulled up stakes in the lower 48 and headed north to Alaska to follow a pioneer dream of claiming land under the Homestead Act. The only land available lay north of Fairbanks near the Arctic Circle where grizzlies outnumbered humans 20 to one. In addition to fierce winters and predatory animals, the Alaskan frontier drew the more unsavory elements of society's fringes. From the beginning, the Cobbs found themselves pitted in a life or death feud with unscrupulous neighbors who would rob from new settlers.

In the summer of 1913, the wooden-hulled brigantine Karluk departed Canada for the Arctic Ocean. At the helm was Captain Bob Bartlett, considered the world’s greatest living ice navigator. The expedition’s visionary leader was a flamboyant impresario named Vilhjalmur Stefansson hungry for fame. Just six weeks after the Karluk departed, giant ice floes closed in around her. As the ship became icebound, Stefansson disembarked with five companions and struck out on what he claimed was a 10-day caribou hunting trip. Most on board would never see him again.
