Physical map of Oregon
Information about the geography of OregonOregon is a state in the Pacific Northwest region of the United States bordering the Pacific Ocean, California, Washington, Idaho, and Nevada. Its northern border lies along the Columbia River and the east along the Snake River.
Two north-south mountain ranges—the Pacific Coast Range and the Cascade Mountain Range — form the two boundaries of the Willamette Valley, one of the most fertile and agriculturally productive regions in the world. Oregon has one of the most diverse landscapes of the fifty states. It is well known for its tall, dense forests and its accessible, scenic Pacific coastline. Less well known are the semiarid scrublands, prairies, and deserts that cover approximately half the state in eastern and north-central Oregon. Its highest point is the summit of Mount Hood, at 3428 m.
