Between 1921 and 1924, Knud Rasmussen led a small band of colleagues in a journey of investigation across the top of North America. The full scientific report of that 20,000-mile trek by dog sled from Greenland to Siberia, known to history as the Firth Thule Expedition, fills ten volumes. This single volume, Across Arctic America, is Rasmussen’s own reworking and condensation of his two-volume popular account written in Danish, and gives the essence of his experience of the Arctic and its people.
