The Willamette Valley ecoregion is a Level III ecoregion designated by the United States Environmental Protection Agency in the U.S. states of Oregon and Washington. Slightly larger than the Willamette Valley for which it is named, the ecoregion contains fluvial terraces and floodplains of the Willamette River system, scattered hills, buttes, and adjacent foothills. It is distinguished from the neighboring Coast Range, Cascades, and Klamath Mountains ecoregions by lower precipitation, lower elevation, less relief, and a different mosaic of vegetation. Mean annual rainfall is 37 to 60 inches (96 to 152 cm), and summers are generally dry. Historically, the region was covered by rolling prairies, oak savanna, coniferous forests, extensive wetlands, and deciduous riparian forests. Today, it contains the bulk of Oregon's population, industry, commerce, and agriculture. Productive soils and a temperate climate make it one of the most important agricultural areas in Oregon.

Camp Adair was a United States Army division training facility established north of Corvallis, Oregon, operating from 1942 to 1946. During its peak period of use, the camp was home to approximately 40,000 persons — enough to have constituted the second largest city in the state of Oregon. The camp was largely scrapped as government surplus following termination of World War II, with a portion of the site reconstituted as "Adair Air Force Station" in 1957. Part of the former Camp Adair is now contained within the E. E. Wilson Wildlife Area, operated by the Oregon Department of Fish and Wildlife (ODFW), with other parts of the camp now incorporated into the city of Adair Village.

Syracuse was a historic community in Linn County, Oregon, United States. It was located along the Santiam River, about two miles west of Jefferson. Syracuse was the first pioneer settlement in Linn County, predating Albany.The area's original inhabitants were the Santiam people of the Kalapuya tribe. Some of the last remaining Santiam people in the area were forced to move to the Grand Ronde Reservation in 1906.Syracuse was founded by Kentucky native Milton Hale, a pioneer who came to the Oregon Country on the Oregon Trail from Burlington, Iowa in 1845. He established a ferry on the Santiam River downstream from what is now Jefferson. Hale's Ferry became an important crossing point for the expansion of Oregon Trail settlers into Linn and Lane counties. The town of Syracuse was on his land claim on the south bank of the river. Syracuse post office was established in 1850, with Jacob S. Conser as the first postmaster. In 1852, the post office moved, and the name was changed to Santiam City, a rival city founded by Samuel S. Miller on the north bank of the river in Marion County. Syracuse and Santiam City eventually lost business to Jefferson, which was founded by Jacob Conser. Santiam City post office was moved and renamed Jefferson in 1861.Both Syracuse and Santiam City across the river were washed out by the Great Flood of 1862 and never rebuilt. No trace of either town exists today.The Simison-Hale Cemetery (aka Syracuse Cemetery or Milton Hale Cemetery) is located near the site of Hale Ferry, probably a short distance west of the townsite. Milton Hale himself is not buried there because there was fear that if the Santiam changed course, it would wash the cemetery away.
