A hundred years ago, when Robert Falcon Scott set out for Antarctica on his Terra Nova expedition, his two primary goals were scientific discovery and reaching the geographic South Pole. Scott was really chasing what contemporary observers call a sufferfest. He set himself up for trouble: Scott brought Manchurian and Siberian ponies that quickly fell through the snow and ice; he planned, in part, for his crew to “man-haul,” meaning that the men would pull sleds full of gear, instead of relying on dogs. Even when Scott’s men faltered, they continued collecting specimens, including rocks. The expedition ended terribly; everybody who made the push to the pole died. Miserable, starving and frostbitten, one of Scott’s last four men killed himself by walking into a blizzard without even bothering to put on his boots. The word “explorer” suggests a morally superior pioneer, a man or woman who braves the battle against nature to discover new terrain, expanding our species’ understanding of the world. “Adventurer,” by contrast, implies a self-indulgent adrenaline junkie, who scares loved ones by courting puerile risk. Sarah Marquis, who perhaps should be seen as an explorer like Scott, born in the wrong age, is 42 and Swiss, and has spent three of the past four years walking about 10,000 miles by herself, from Siberia through the Gobi Desert, China, Laos and Thailand, then taking a cargo boat to Brisbane, Australia, and walking across that continent. Along the way, like Scott, she has starved, she has frozen, she has (wo)man-hauled. She has pushed herself at great physical cost to places she wanted to love but ended up feeling, as Scott wrote of the South Pole in his journal: “Great God! This is an awful place.” http://youtu.be/AjfCIRiUAw8
