Zebulon Pike trip and Pawnee Indian Village correspondence
Date: January 7, 1891-January 18, 1928
This correspondence addresses explorer Zebulon Pike's 1806 expedition to the West, particularly Pike's visit to the Pawnee village located in present-day Republic County, Kansas. The correspondence spans the years 1891 to 1928, and covers the details of the trip, as well as the most likely location of the Pawnee village. One of the correspondents, naturalist and historian Elliott Coues, edited a popular edition of the Journals of Lewis and Clark (1893) and published The Travels of Zebulon Pike in 1895.
