Scott Wallace covers the environment, vanishing cultures, and conflict over land and resources for major media organizations. His assignments have taken him from encampments of native reindeer herders in the Arctic to combat missions in the jungles of Central America. Formerly a correspondent for the Guardian and CBS News, Wallace has written several stories for National Geographic magazine about the Amazon rain forest. He is author of the New York Times best-selling book, The Unconquered: In Search of the Amazon’s Last Uncontacted Tribes, based on a National Geographic assignment into the deepest redoubts of the rain forest to track and protect a mysterious, seldom-glimpsed tribe. He is a recipient of the Explorers Club's prestigious Lowell Thomas Award and an expert for National Geographic Expeditions.
