Oregon, constituent state of the United States of America. Oregon is bounded to the north by Washington state, from which it receives the waters of the Columbia River; to the east by Idaho, more than half the border with which is formed by the winding Snake River and Hells Canyon; to the south by Nevada and California, with which Oregon shares its mountain and desert systems; and to the west by the Pacific Ocean, which produces the moderate climate of Oregon’s western lands. The capital is Salem, in the northwestern part of the state.
Admitted to the union as the 33rd state on February 14, 1859, Oregon comprises an area of startling physical diversity, from the moist rainforests, mountains, and fertile valleys of its western third to the naturally arid and climatically harsh eastern deserts. Mountains, plateaus, plains, and valleys of different geologic ages and materials are arrayed in countless combinations, including such natural wonders as the Columbia River Gorge, Oregon Caves National Monument, Crater Lake National Park, the majestic snow-covered peaks of the Cascade Range, and the central Oregon “moon country” (lava fields that served as a training site for astronauts in the U.S. space program in the 1960s). The name Oregon is thought to be Native American in origin.
Oregon has nine major landform regions, of which the forest-blanketed Coast Range, which borders the Pacific Ocean from the Coquille River northward, is the lowest. Its elevations are generally below 2,000 feet (600 metres), but Mount Bolivar, east of Port Orford, reaches 4,319 feet (1,316 metres).

The Klamath Mountains, which extend from California, lie south of the Coast Range and west of the Cascades. Composed of ancient resistant rocks, they have had a complicated geologic history. They are higher and more rugged than the Coast Range and lack the north-south orientation. The Rogue River, bisecting the area, provides the major drainage. Thick forests grow on these mountains, which also contain rich mineral deposits. Mount Ashland, which reaches 7,532 feet (2,296 metres), is the tallest peak in Oregon’s Klamath Mountains.
The Willamette valley is essentially an alluvial plain produced by burying stream-modified lowland with enormous quantities of sediments brought down by tributary streams from the bordering mountains. The low, hilly areas in the central and northern portions are composed of resistant rocks. This valley contains the prime land of the state, about one-tenth of its total acreage, and its soils support intensive agriculture.
