The carving of a deep, steep-sided valley, typically by a river cutting downward through resistant rock faster than the surrounding land erodes outward, often aided by regional uplift that steepens the stream's gradient over geological time. The Grand Canyon's mile-deep gorge is the process's best-known result.
