It would be easy to imagine that after centuries of traverses, treks, and summits there would be no firsts left. For explorers, finding new ground to cross is almost as difficult as the actual crossing. But that's not stopping anyone: Only a month in, this already looks to be a banner year for elite adventurers, who plan to walk the length of a great river, motorcycle in a very large circle, and summit one of the most dangerous mountains on Earth. Here are the expeditions we'll be watching.
Levison Wood's walk the length of the Nile
British explorer, writer, photographer, and former paratrooper Levison Wood is attempting to become the first person to walk the 4,258-mile length of the Nile. Accompanied by his guide, Boston, a former rebel from the Congo, he kicked off his journey in December 2013 at the river's Rwandan source and in late January 2014 was nearing Kampala, the capital of Uganda, on his way to Alexandria, Egypt. A documentary on the trek will air in 2015 on Britain's Channel 4 and Animal Planet in the United States.
