Question: Which town at the southern end of the Willamette Valley hosts the University of Oregon College of Arts and Sciences?
Context: The camas pocket gopher ("Thomomys bulbivorus"), also known as the camas rat or Willamette Valley gopher, is a rodent, the largest member in the genus "Thomomys", of the family Geomyidae.  First described in , it is endemic to the Willamette Valley of northwestern Oregon in the United States.  The herbivorous gopher forages for vegetable and plant matter, which it collects in large, fur-lined, external cheek pouches.  Surplus food is hoarded in an extensive system of underground tunnels.  The dull-brown-to-lead-gray coat changes color and texture over the year.  The mammal's characteristically large, protuberant incisors are well adapted for use in tunnel construction, particularly in the hard clay soils of the Willamette Valley.  The gophers make chattering sounds with their teeth; males and females make purring (or crooning) sounds when they are together, and the young make twittering sounds.  Born toothless, blind and hairless, the young grow rapidly before being weaned at about six weeks of age. The Willamette Meteorite, officially named Willamette, is an iron-nickel meteorite discovered in the U.S. state of Oregon.  It is the largest meteorite found in North America and the sixth largest in the world.  There was no impact crater at the discovery site; researchers believe the meteorite landed in what is now Canada or Montana, and was transported as a glacial erratic to the Willamette Valley during the Missoula Floods at the end of the last Ice Age (~13,000 years ago).  It was long held sacred by indigenous peoples of the Willamette Valley, including the federally recognized Confederated Tribes of the Grand Ronde Community of Oregon (CTGRC).  The indigenous peoples referred to this stone with the name "Tomonowos" (the visitor from the sky). Eugene ( ) is a city of the Pacific Northwest located in the U.S. state of Oregon.  It is located at the southern end of the Willamette Valley, near the confluence of the McKenzie and Willamette Rivers, about 50 mi east of the Oregon Coast. Willamette Valley Vineyards is an American winery located in Turner, Oregon.  Named after Oregon's Willamette Valley, the winery is the leading producer of Pinot noir in Oregon, and also produces Dijon clone Chardonnay and Pinot gris.  In 2016, the winery was the largest producer of Riesling wine in the Willamette Valley. The University of Oregon College of Arts and Sciences (CAS) is a public school of science and liberal arts at the University of Oregon (UO) in Eugene, Oregon, United States.  The main offices of the college are located in Friendly Hall on the UO campus.  The college serves an estimated 11,000 undergraduates at any given time. The Chehalem Mountains are a mountain range located in the Willamette Valley in the U.S. state of Oregon.  Forming the southern boundary of the Tualatin Valley, the Chehalems are the highest mountains in the Willamette Valley.  Composed of a single land mass that was uplifted by tectonic forces, the mountain range includes several spurs and ridges such as Parrett Mountain, Ribbon Ridge, and Bald Peak.  The range extends from the Willamette River east of Newberg northwest to the foothills of the Oregon Coast Range south of Forest Grove.  The highest peak in the Chehalem Mountain Range is Bald Peak, rising to 1629 ft , which is also the highest peak point within the Willamette Valley. The Willamette Valley, also known as the Willamette Valley Express, was a passenger train operated by Amtrak between Portland, Oregon and Eugene, Oregon, in the early 1980s.  The name came from the Willamette Valley region which the train ran through. The Eola-Amity Hills AVA is an American Viticultural Area located in Polk County and Yamhill County, Oregon.  It is entirely contained within the Willamette Valley AVA, and stretches from the city of Amity in the north to Salem in the south.  The Eola and Amity hills cover an area west of the Willamette River approximately 15 mi long by 6 mi wide.  The Eola-Amity Hills area benefits from steady winds off the Pacific Ocean that reach the Willamette Valley through the Van Duzer Corridor, a gap in the Oregon Coast Range, moderating the summer temperatures.  The Eola Hills were named after the community of Eola, whose name was derived from "Aeolus", the Greek god of the winds. The Willamette Valley AVA ( ), is an American Viticultural Area which lies in the Willamette Valley of Oregon.  The AVA is the wine growing region which encompasses the drainage basin of the Willamette River.  It stretches from the Columbia River in the north to just south of Eugene in the south, where the Willamette Valley ends; and from the Oregon Coast Range in the west to the Cascade Mountains in the east.  At 5200 sqmi , it is the largest AVA in the state, and contains most of the state's wineries; approximately 200 as of 2006.  The boundaries of the Willamette Valley AVA were established in 1984, and since then six new, smaller AVAs have been created within the northern portion of Willamette Valley AVA.  The Willamette Valley has a cool, moist climate, and is recognized worldwide for its Pinot noir. 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.
