Portal:Oregon/Intro
Oregon is a state in the Pacific Northwest region of the United States. It borders the Pacific Ocean on the west, Washington on the north, Idaho on the east, and California and Nevada on the south. The Columbia and Snake Rivers form, respectively, much of its northern and eastern borders. Between two north-south mountain ranges in western Oregon—the Oregon Coast Range and the Cascade Mountain Range—lies the Willamette Valley, the most densely populated and agriculturally productive region of the state.
Oregon has one of the most diverse landscapes of any state in the U.S. It is well known for its tall, dense forests; its accessible and scenic Pacific coastline; and its rugged, glaciated Cascade volcanoes. Other areas include semiarid scrublands, prairies, and deserts that cover approximately half the state in eastern and north-central Oregon.
Oregon's population in 2010 was about 3.8 million, a 12% increase over 2000. Oregon's population is largely concentrated in the Willamette Valley, which stretches from Eugene through Salem and Corvallis to Portland, Oregon's largest city.
The origin of the name Oregon is unknown. One account, advanced by George R. Stewart in a 1944 article in American Speech, was endorsed as the "most plausible explanation" in the book Oregon Geographic Names. According to Stewart, the name came from an engraver's error in a French map published in the early 1700s, on which the Ouisiconsink (Wisconsin) River was spelled "Ouaricon-sint", broken on two lines with the -sint below, so that there appeared to be a river flowing to the west named "Ouaricon".
