In this special Expeditions issue of Asian Geographic, we take a look at some of the most awe-inspiring expeditions and exploration missions across the continent. Journey to a remote part of northern Siberia, where the greatest concentration of mammoth tusks is concentrated. In this tough, icy terrain, palaeontologists and ivory hunters are vying for these valuable remains. Explore the past 101 years of the Trans-Siberian Railway, which covers vast swaths of terrain across the continent. In connection with Asian Geographic's forthcoming expeditions in 2017, discover the history of the Silk Road, and the routes of the earliest explorers. Find out more about the Asian space race, and technological advances to harness resources outside our atmosphere. We also profile several activists who are using their respective expeditions to improve public environmental awareness. We feature the stunning work of Michael Yamashita, who has documented the legacies of explorers such as Marco Polo and Zheng He.
