In 2010, explorer Sarah Marquis set out on a solo walk from Siberia to Australia. Over the course of three years and 10,000 miles, she braved subzero temperatures and sandstorms, and was harassed by drunk nomads and drug dealers. She writes about the adventure in a new book called "Wild By Nature."
