Expedition Unknown

On May 24, 1869 a one-armed Civil War veteran, John Wesley Powell, and a ragtag band of nine mountain men embarked on the last great quest in the American West. The Grand Canyon, not explored before, was as mysterious as Atlantis - and as perilous. The 10 men set out from Green River Station, Wyoming Territory, down the Colorado in four wooden rowboats. Ninety-nine days later, six half-starved wretches came ashore near Callville, Arizona.

In 1845, Sir John Franklin and his men set out to "penetrate the icy fastness of the north, and to circumnavigate America." And then they disappeared. The truth about what happened to Franklin's ill-fated Arctic expedition was shrouded in mystery for more than a century. Then, in 1984, Owen Beattie and his team exhumed two crew members from a burial site in the North for forensic evidence, to shocking results. But the most startling discovery didn't come until 2014, when a team commissioned by the Canadian government uncovered one of the lost ships: Erebus.

Gripping and often poetic, Alone Against the North is a classic adventure story of single-minded obsession, physical hardship, and the restless sense of wonder that every explorer has in common. What Shoalts discovered as he paddled downriver was a series of unmapped waterfalls that could easily have killed him. Just as astonishing was the media reaction when he got back to civilization. He was feted by the Royal Canadian Geographical Society and congratulated by the Governor General. People were enthralled by Shoalts’s proof that the world is bigger than we think.

It began with a secret mission, no expenses spared. Spain, plotting to break Portugal’s monopoly trade with the fabled Orient, set sail from a hidden Mexican port to cross the Pacific - and then, critically, to attempt the never-before-accomplished return, the vuelta. Four ships set out from Navidad, each one carrying a dream team of navigators. The smallest ship, guided by seaman Lope Martín, a mulatto who had risen through the ranks to become one of the most qualified pilots of the era, soon pulled far ahead and became mysteriously lost from the fleet.
