The Oregon Trail: Sketches of Prairie and Rocky-Mountain Life
The Oregon Trail: Sketches of Prairie and Rocky-Mountain Life (also published as The California & Oregon Trail) is a book written by Francis Parkman. It was originally serialized in twenty-one installments in "Knickerbocker's Magazine" (1847–49) and subsequently published as a book in 1849. The book is a first-person account of a 2-month summer tour in 1846 of the U.S. states of Nebraska, Wyoming, Colorado, and Kansas. Parkman was 23 at the time. The heart of the book covers the three weeks Parkman spent hunting buffalo with a band of Oglala Sioux.
