The Expedition Journals feature three travel journals bound in a single volume. The first two document William Dunbar's expedition up the Red and Ouachita Rivers to the Hot Springs of Arkansas in 1804-1805. Although few contemporary locations are named, they include numerous coordinates that researchers may use to track the journey. "Journal... to the Mouth of the Red River" furnishes particularly lush descriptions of the settlers (e.g. 10/21/1804) and indigenous peoples (11/24/1804) in the region. The second journal records technical data from the expedition, including a thermometrical log. Both journals dovetail nicely with that of traveling companion, George Hunter, also available at the APS (Mss.B.H912).; The final journal recounts an expedition to explore the geography of the Mississippi River led by Lt. Zebulon Montgomery Pike between 1805-1806. The Pike journal provides a daily account of the activities of the expedition during an early exploration into present day Minnesota. Notably, that journal includes significant attention to exchanges between settlers and local indigenous tribes (e.g. 9/3/1805, 9/10/1805, 9/24-25/1805). That volume has been printed with variations and omissions in An Account of Expeditions to the Sources of the Mississippi and through the Western Parts of Louisiana... (Philadelphia, 1810), and it was edited in Donald Jackson, ed., The Journals of Zebulon Pike: with Letters and Related Documents (Norman, Okla., 1966). Bound together, the Dunbar and Pike volumes ought to interest a range of scholars researching U.S. exploration and Native America in the early national period.
