With the days of the great buffalo herds as his focal point, the author looks at the Northern Plains through the lenses of geology, paleontology, biology, and especially history. He describes how the land was formed, chronicles the fantastic prehistoric animals that came and went, and tells the stories of the humans--natives and settlers alike--who have lived on this land.
After prehistoric narrative at the beginning, the pace picked up and it was an excellent book. Author provided background of historical events form early 1700's forward and documented most with a very interesting note section. He also visited many of the landmarks that are mentioned along with his feelings about being at those physical locations. Recommend to anyone who wants to understand the native American past 300 years in northern plains as well as the fur trading era all the way to the white encroachment and 1950's building of the Missouri River dams and the affect on SD/ND tribes and reservation.
