Camp Withycombe, located in Clackamas County, Oregon, United States, was originally established as Camp Benson after Governor Frank W. Benson, but was later renamed Camp Withycombe during World War I for Governor James Withycombe. Originally known as the Clackamas Rifle Range, it was established as a training camp in 1909 and expanded during World War I, during which it served as a headquarters for the National Guard, a central supply depot and training center. Pendleton, Oregon photographer Walter S. Bowman photographed Camp Benson in the early 20th century.
