A superb example of careful and diligent research, this publication concentrates on the Lewis and Clark travels in North Dakota. Through the explorers' journal entries, readers follow the Missouri River, the changing seasons, and encounters with new people and cultures. The journal entries are easy to read, thanks to the author's extensive but unobtrusive notes about the flora, fauna, geology and geography. Those notes also assist the reader through creative spelling, awkward grammar, and colloquial expressions. This book is a noteworthy travel guide through history.
