An extraordinary book of aerial photographs of mountains, glaciers and ice accompanied by explanatory text by two devoted glaciologists. Much too beautiful to be called a textbook, this collection of striking black-and-white photographs introduces the major surface features, varieties of glaciers and diversity of ice. With a glossary and annotated bibliography for further reading. An obvious choice for mountaineers and polar explorers, this book will appeal to any curious traveler -- or even anyone who has ever looked out the window of an airplane en route over Greenland. In cooperation with the International Glaciological Society. A modern classic, originally published in 1971.  (SCI07, $35.00)
