Hells Canyon is a ten-mile-wide (16 km) canyon in the Western United States, located along the border of eastern Oregon, western Idaho, and a small section of eastern Washington. It is part of the Hells Canyon National Recreation Area which is also located in part of the Wallowa-Whitman National Forest.[2] It is North America's deepest river gorge at 7,993 feet (2,436 m),[3] running deeper than the Grand Canyon in Arizona.[4]
The canyon was carved by the waters of the Snake River, which flows more than one mile (1.6 km) below the canyon's west rim on the Oregon side and 7,400 feet (2,300 m) below the peaks of Idaho's Seven Devils Mountains to the east. This area includes 214,000 acres (87,000 ha) of wilderness.[5] Most of the area is inaccessible by road.[6]
