Back to the Columbia River

The Columbia River Gorge is a long winding canyon, cut by the Columbia River, that extends approximately 80 miles (130 km) from the Cascade mountain range to the Pacific Ocean. The gorge marks the boundary between Oregon and Washington State. It is the only navigable water route between the Columbia River Plateau and the ocean. Because of it varying elevation and levels of rainfall, the gorge has many diverse ecosystems represented along its course and is part of the larger Columbia River Gorge National Scenic Area.
