Admited to the Union as the 33rd state on Feb. 14, 1859, Oregon comprises an area of startling physical diversity, from the moist rain forests, mountains, and fertile valleys of its western third to the naturally arid and climatically harsh eastern deserts. Mountains, plateus, 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 “moon country” of central Oregon. The name Oregon is thought to be Indian in orgin.
To the north of the state’s 97,073 square miles (251,419 square kilometres)of land and inland water lies Washington, from which Oregon receives the waters of the Columbia River; to the east, Idaho, more than half of the border with which is formed by the winding Snake River and its Hells Canyon, the deepest gorge on the North American continent; to the south, Nevada and California, with which Oregon shares its mountain and desert systems; and, to the west, the Pacific Ocean, which produses the moderate climate of Oregon’s western lands.
The forested mountains of western and northeastern Oregon have supplied the traditional core of the state’s economy. Its many forest-product plants produce more than one-fith of the nation’s softwood lumber, much of its soft plywood, and large quantites of hardboard, pulp, and paper. Nationally, Oregon ranks first in the production of wood products. In addition, the multipurpose development of the Columbia River system provides huge quantites of electrcity, water for irrigation and industry, shipping channels, and water for recreation. The hearthland the major cities of Portland, Eugene, and Salem (the capital) and a rich diversified agriculture.
PHYSICAL AND HUMAN GEOGRAPHY
THE LAND.Relief.oregon has nine major landform regions. Of them the forest-blanketed Coast Range, which borders the Pacific Ocean from the Coquile River northward, is the lowest. Its elevations are usually below 2,000 feet, but Marys Peak, southwest of Corvallis, reaches 4,098 feet (1,249 metres).
The Klamath Mountains, which extend from California, lie south of the Coast Range and west of the...
