Using newly declassified documents, this book explores why U.S. military leaders after World War II sought to monitor the far north and understand the physical environment of Greenland, a crucial territory of Denmark. It reveals a fascinating yet little-known realm of Cold War intrigue and a delicate diplomatic duet between a smaller state and a superpower amid a time of intense global pressures. Written by scholars in Denmark and the United States, this book explores many compelling topics. What led to the creation of the U.S. Thule Air Base in Greenland, one of the world’s largest, and why did the U.S. build a nuclear-powered city under Greenland’s ice cap? How did Danish concern about sovereignty shape scientific research programs in Greenland? Also explored here: why did Denmark’s most famous scientist, Inge Lehmann, became involved in research in Greenland, and what international reverberations resulted from the crash of a U.S. B-52 bomber carrying four nuclear weapons near Thule in January 1968?

As polar exploration reached its zenith, and in the same month that Captain Robert Falcon Scott perished in Antarctica, four young scientists from Zurich took ship for Greenland. Though they had little previous experience of arctic travel, their ambition was to achieve the first west-to-east crossing of the northern hemisphere’s largest ice cap, making scientific observations along the way. Few outside Switzerland have heard of this expedition or its leader, the meteorologist Alfred de Quervain, in spite of its success. In thirty-one days in the summer of 1912, the party sledded across 640 kilometres of untracked snow and ice. Nobody died or fell into a crevasse, although there were some near misses. The voyage was more than a well-executed feat of arctic travel: de Quervain and his colleagues collected data still used today by scientists researching the effects of climate change on Greenland’s ice cap. De Quervain’s popular account of his adventures, published in German in 1914, is both a minor classic of exploration literature and a sympathetic portrayal of life in Greenland’s remote coastal settlements in the early twentieth century. Published to coincide with the expedition’s 110th anniversary, Across Greenland’s Ice Cap includes the explorer’s original text, translated into English by his daughter and son-in-law; a historical and biographical introduction by Martin Hood; reflections on the journey’s scientific legacy by the geographers Andreas Vieli and Martin Lüthi; and a treasure trove of hand-tinted lantern slides reproduced in full colour.

The history of the Cold War has focused overwhelmingly on statecraft and military power, an approach that has naturally placed Moscow and Washington center stage. Meanwhile, regions such as Alaska, the polar landscapes, and the cold areas of the Soviet periphery have received little attention. However, such environments were of no small importance during the Cold War: in addition to their symbolic significance, they also had direct implications for everything from military strategy to natural resource management. Through histories of these extremely cold environments, this volume makes a novel intervention in Cold War historiography, one whose global and transnational approach undermines the simple opposition of “East” and “West.”
