The Columbia River Gorge is a canyon of the Columbia River in the U.S. Pacific Northwest. Up to 4,000 feet (1,200 m) deep, the canyon stretches for over 80 miles (130 km) as the river winds westward through the Cascade Range forming the boundary between the State of Washington to the north and Oregon to the south. The gorge holds federally protected status as a National Scenic Area called the Columbia Gorge National Scenic Area and is managed by the Columbia River Gorge Commission and the US Forest Service.
