canyon walls
Ravine's vertical boundaries
Canyon walls are the steep, often vertical rock faces that form the sides of a canyon.
The phrase appears frequently in descriptions of dramatic landscapes, especially the American Southwest: The canyon walls glowed orange at sunset.
Canyon walls may rise hundreds or thousands of feet, their layered rock revealing geological history.
