steep rock

They had reached a line of tall cliffs, where a steep rock-fall divided off the plain from the edge of the mountains.

The steep rock faces were covered with a harsh brown moss, which, except when wet, gave an excellent foothold to the climber.

Once they came to a steep rock, to descend which they must make a ladder of creeping vines.

The western bastion is built on a steep rock, whence there is a fall of three hundred feet on to the roofs of the houses below.

A well-kept, serpentine path winds up the steep rock, and there is a mossy stone seat at every bend.
