<div dir="auto">I have locally many near vertical exposed rock features of which even locals don't know if they are man-made or natural.

Artificial rock faces in quarries and open pit mines, called berms, are created due to blasting. The faces are typically inclined 60-70° with drops of max. a few tenth of meters. This fundamental difference might be best taken into account by using man_made=embankment for these.<br>

I have to contradict in one point. I know of a lot of former and present quarries where the faces are inclined 90° and ten'ths of meters high. Maybe this is not so much the point for open pit mines. But tagging should be ready to cope with non-natural steep faces. I see no problem however in using some man_made key for this. "embankment" might be misleading, however. What about man_made=cliff for non-natural steep drops?<br>
<br>
The renderer then could decide whether to choose differentiating drawing. (Most probably he won't do so).<br>
