"For the last decade, Gretel Ehrlich has been obsessed by an island, a terrain, a culture, and the men and women who long for and love the complex frailties and treacherous beauty of a world defined by ice." "Greenland, the world's largest island, 840,000 square miles in extent, is covered by the largest continental ice sheet in the world." "Her guide, her inspiration, her companion in spirit was the great Danish-Inuit explorer and ethnographer Knud Rasmussen. Between 1902 and his death in 1933 he launched seven expeditions: to record the unknown history and customs of the nomadic Eskimos; to chronicle the skills, beliefs, and crafts that made life in this climate possible and a matter of grace. For Rasmussen, "all true wisdom is only to be found far from the dwellings of man, in great solitudes." As she followed his trail, Ehrlich was to find the things that can open the mind to what is hidden from others. This Cold Heaven is at once a distillation of her many journeys, a path into a world divided into darkness and light and, finally, an attempt to capture the clarity that blinds us with surprise."--BOOK JACKET.
