Query: ANWAR and how it was done before

This book is a masterpiece. If you worry about opening the arctic national refuge for oil, read this book. This book shows what happened 70 years ago to the Native people, to the workers, to the land. It tells the story from the point of view of a Native Chief, who saw the world changing, and gave his wisdom -- much like Chief Seattle, to his grandsons. It is well written, well documented, and belongs in archives with great historical fiction. The research in this book reminds one of Clancy or Michner. This book will be on my Christmas list.
