For a few moments he contemplated the rock floor between his feet.

The rock floor, the lack of movement, and the darkness told him that much before he even opened his eyes.

And there was no body on the rock floor.

There were at least ten thousand people on the rock floor now.

But he did not land hard on the rock floor, for she held him up.

There was a join in the solid rock floor, and, great heavens!

Someone ran lightly across the rock floor to a point just below him.

He raised the radio above his head and sent it crashing into the rock floor.

There was nothing but a wooden board between him and the rock floor, thousands of feet below.

If the natural rock floor were smoothed just a little, it would be quite level.
