sheer drop

It was like looking at a door that opened onto nothing but a sheer drop.

The sheer drop of the ice fall lay right at her back.

It opened right outside, with a sheer drop to the ground.

It was a sheer drop off the side of the stairs.

"And on the other side of this wall, there is only a sheer drop?"

Only eight feet wide here, and a sheer drop off to her right.

Below them was a sheer drop of more than a hundred feet.

After a while, it was almost a sheer drop on either side.

For to the left was a sheer drop, far into the valley below.

There was a sheer drop down to the valley below, or so it seemed to the boy.
