Query: A Classic

"Across Arctic America" is the report of the Fifth Thule Expedition, led by Knud Rasmussen in the 1920s. Rasmussen does an excellent job of describing the material culture, ways and beliefs of the Eskimos (now called Inuit) he encountered across the Arctic from Greenland to Alaska, at a time when they were still living the nomadic life of hunter-gatherers, as they had done for centuries before. Rasmussen's descriptions are detailed, his documentation of songs and poems that might otherwise have been lost are valuable, as are his records of the differences among subgroups he encountered. In addition, the author's respect for the people who are his research subjects is evident throughout this book.
