A long deep, relatively narrow steep-sided valley confined between lofty and precipitous walls in a plateau or mountainous area, often with a stream at the bottom; similar to, but largest than, a gorge. It is characteristic of an arid or semiarid area (such as western U.S.) where stream downcutting greatly exceeds weathering. (Source: BJGEO)
