The Rivers of America series continues its highly individual reportage on our waterways, this time on the ""most necessary...most hated...last discovered"" river, and an absorbing story it is of ""American westering"". The accent is on the past, the exploits of the early travelers, the savage hardships they encountered along the river. From idwell, Fremont, Heatings, to the Donner epic, the Mormone, gold, silver, transportation, communications, the railroad, cattle, farming -- this makes colorful, adventurous, exciting reading of a virtually unconquerable frontier, filled with excellent story telling and dramatic history.
