The Klamath Mountains, a series of ranges in the southern corner of Oregon, run from the southern coast into northern California. The Klamath Mountains connect in the southeastern part of the state to the Cascade mountains that run north to south between the Willamette River on the east the Deschutes River on the west that runs down nearly the center of the state.
Between the Coastal Range along the northern part of Oregon's coast and the Cascade Mountains runs the Willamette River and Willamette Lowlands, a stretch of fertile land. The lowlands end at Oregon's northern border where they meet with the Columbia River Gorge that separates Washington and Oregon. The Columbia River flows along much of the border, creating the Columbia Plateau in the eastern-central part of the state.
The Blue-Wallowa Mountains run along the northeastern corner of Oregon, and the Steens Mountains make up the southeastern corner, giving much of eastern Oregon a rugged landscape.Learn more about The West
