"In the taxonomy of travelers, 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. The former, obviously, is the far better title, but it’s tough to claim these days. The world is Google-mapped. Reaching the actual virgin territory of space or the deep ocean requires resources that few possess. In short, the noble fig leaf of terra incognita has fallen away and laid bare the peripatetic, outsize bravado of Scott’s kindred spirits. The resulting itineraries are pretty strange. We now have guys like Felix Baumgartner sky-diving from a balloon-borne capsule at 128,100 feet.
Baumgartner falls squarely — and for more than four minutes, breaking the speed of sound — into the adventurer camp. But then there’s Sarah Marquis, who perhaps should be seen as an explorer like Scott, born in the wrong age. She 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.” Despite planning a ludicrous trip, and dying on it, Scott became beloved and, somewhat improbably, hugely respected. Marquis, meanwhile, can be confounding. “You tell people what you’re doing, and they say, ‘You’re crazy,’ ” Marquis told me. “It’s never: ‘Cool project, Sarah! Go for it.’ ” Perhaps this is because the territory Marquis explores is really internal — the nature of fear, the limits of stamina and self-reliance and the meaning of traveling in nature as a female human animal, alone."
