Hells Canyon is a 10-mile (16 km) wide canyon located along the border of eastern Oregon, eastern Washington and western Idaho in the United States. It is North America's deepest river gorge at 7,993 feet (2,436 m) and part of the Hells Canyon National Recreation Area.
The canyon was carved by the waters of the Snake River, which flows more than 1 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 range to the east. Most of the area is inaccessible by road.

“In a world that holds books and babies and canyon trails, why should one condemn oneself to live day-in, day-out with people one does not like, and sell oneself to chaperone and correct them?”

Of his friends’ hells into a pigeonhole—
He hung each disparate anguish on the spits
Parboiled and roasted in his own withering soul.”
