The 'natural' key is used for both 'natural' and 'unnatural' objects!

For example 'wood' is used where the trees have been grown from manually collected seed in an artificial light, automatically provided watering with liquid food, within a temperature and humidity controlled environment, and then manually planted out.

Another example is 'water' used in so many man made dammed areas.

In general a cliff is more vertical and taller than an embankment.

I would opt for the present use... recreation?

If unused at present then the disused: etc would be practical.
Possibly both past and present use can be tagged together.
