A hand drawn map of the town of Joseph from J. H. Horner’s work, Wallowa River and Valley (Page 820). The manuscript details the history of the Wallowa Valley region in northeastern Oregon from approximately 1805 through 1950. The document includes extensive details on the origins of many place names in the region. The manuscript also includes a history of the Nez Percé people and their cultural traditions which Horner wrote in collaboration with Otis Halfmoon. Topics covered in the manuscript include Chief Joseph and the events of the Nez Percé war of 1877, settlement of the Wallowa Valley region, and local participation in World War I and World War II. John Harland Horner (1870-1953) was born in Kansas City, Missouri, and moved to Enterprise, Oregon, in 1911. He served as Wallowa County's deputy assessor from 1918 to 1924, before being elected county assessor in 1924. Horner also had a long-standing interest in the history of Wallowa County. For more than thirty years, he collected historical information and interviewed most of the area's early settlers and local Native Americans.
