Spirited and vividly written account chronicles the courageous deeds of men in frail boats who dealt with a mighty river and its raging rapids as they explored the last great unknown stretch of land in the continental U. S. Enhanced with 20 of the author’s charming illustrations, the volume also includes nearly 200 contemporary photographs that provide an accurate view of the landscape and terrain encountered by the historic Powell expedition of 1871. A splendid tribute to the men involved in an extraordinary and scientifically rewarding mission, this volume will be invaluable to students of American history and prized by environmentalists and armchair adventurers alike.
