steep walls
Near-vertical rock surfaces
Steep walls are walls that rise at a sharp, nearly vertical angle.
The phrase appears most often in descriptions of canyons, cliffs, and gorges where rock faces climb dramatically: The steep walls of the canyon blocked out the afternoon sun.
In architecture or construction, it may describe any wall built at an unusually sharp incline rather than truly vertical.
