The sheer cliff took up half his field of view.

They come to a cliff rather lower and less sheer than that behind.

Above me was a hundred feet of almost sheer cliff.

But there was still that sheer cliff and the men on the top could do nothing to help.

The view over the side took her breath away with its sheer cliffs.

But they were standing at the very edge of a sheer cliff.

Behind them, they could see a sheer cliff which was also lost in darkness beyond a certain point.

He was standing in the middle of the road, the sheer cliffs rising on either side.

Back outside again, they gazed up at the sheer cliffs behind the building.

They're going up sheer cliffs, it looked to me, like it's a walk in the park.
