This thesis describes the archaeological site content and integrity of the Copeland site (35BE90) in Corvallis, Oregon. The Copeland site is owned by the Benton County Historical Society and is the future home of the Benton County Historical Museum. In 2001, an Oregon State University archaeological field school was conducted to test for the presence of the residential houses and commercial businesses that once occupied the Copeland site. The archaeological excavation revealed the presence of both the residential and commercial usage that occurred at the Copeland site. Excavation also revealed that while the integrity of the site has been disturbed by commercial activities the integrity has not been completely destroyed. Finally, recommendations are made concerning further archaeological exploration of the site. / Graduation date: 2006
