The handsome diary of an expedition, combining 50 striking color photographs by Boyd Norton and illuminating text by the incomparable Peter Matthiessen, a portrait of the world's oldest and deepest freshwater lake and the industrialization that threatens its future. It's as big as Belgium. With excerpts on the history and biology of Baikal and translations of Buryat myths and folklore. A portion of the royalties go to Baikal Watch.  (SIB02, $18.00)
