What Are Oregon's Major Landforms?

Oregon's major landforms include the Oregon Coast Range, the Cascade Range, the Columbia River Gorge, the Blue-Wallowa Mountains and the Klamath Mountains. Oregon has a diverse landscape that includes basins, plains, semidesert ranges, rugged highlands, mountains, lakes, rivers, beaches, cascades, waterfalls, volcanoes and more.

The Oregon Coast Range extends over 200 miles along the Pacific Ocean. Its average elevation is about 1,500 feet above sea level, and the range's widest point is 60 miles across.

The Cascade Range extends through Southern British Columbia, Washington, Oregon and Northern California and includes several volcanic mountains. The range contains Mount Hood, which is Oregon's highest peak at 11,249 feet.

The Columbia River Gorge is a scenic canyon of the Columbia River. On the Oregon side, it has over 90 waterfalls.

The Blue-Wallowa Mountains are east of the Cascades and include a collection of mountain ranges. Some of the peaks reach close to 10,000 feet. The eastern side falls into Hells Canyon, the deepest river gorge in North America.

The Klamath Mountains span from northern California to southwest Oregon. The unique geology in the area makes the forests in the Klamath Mountains biologically diverse. The area is rugged and wild with a low percentage of human settlement. Much of the area is managed by the U.S. Forest Service, and there are several national forests in the region.
