That run is about eight miles long with a drop of 3,900 feet.

The original natural falls had a drop of only about five feet.

From its edge, there was a drop of a dozen feet to the ground.

I ran the 20 feet to the final, highest 100 foot drop, and started up after them.

A drop of at least 2 feet is required or the system may not be feasible.

"That's a drop of five hundred feet and into a wild river!"

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

Before them was a drop of two hundred feet to the valley beneath.

It was a drop of less than 10 feet to the ground, then only a few yards to the waiting vehicle.

Even a drop of several hundred feet didn't bother her anymore.
