rock face

Seams of coal run like black ribbons through sheer rock face.

As the madman was working over here, I climbed and slipped, and cut steps in the rock face of the cliff, on yon side.

On one side of it a huge precipice presents a bare rock face from which the water trickles into a little lake at the base.

You see, if the kid had not held fast, I'd have gone right down the rock face and don't know where I'd have stopped.

My poor Bart broke into an account of all that had occurred, but that rock-face never softened for an instant.

There was a rough pathway constructed up its face upon this side, and at the top were three tiers of holes bored in the rock face.
