The mountain fell away in a steep tim to either side.
It seemed that half the mountain was falling upon them.
I just don't see any reason to believe that the mountain fell down here.
It felt as if a mountain had fallen on top of him.
"Oh, my friend, all the mountain would have fallen on us but for your great strength."
If a mountain falls on you it'll be a bit of a knock.
In some places the mountains fall directly into the sea.
Though the earth give way and the mountains fall into the sea, I will always love you.
I tell you the truth, it was as if a mountain had fallen on me.
The mountain fell away below me and loomed up far above.
