Situated on the south bank of the Willamette River, Champoeg's acres of forest, fields, and wetlands recreate the landscape of a bygone era. Once a thriving commerce center the city of Champoeg was wiped off the map in the famous flood of 1861 when the Willamette River rose 55 feet above its summer level. Among the park's attractions are a visitor center, the Newell House, and Pioneer Mothers Log Cabin museums. The park also includes the Historic Butteville Store founded in 1863. It is considered the oldest operating store in Oregon. The store is the last commercial vestige of the once thriving Willamette River community of Butteville.
