I'm mainly dealing with historic mining. Spoil heaps of historic mining 
however are very real. And they often developed directly in front of an 
adit at the base or slope of a mountain. I've seen a lot of them and 
because of their origination history they are at the flank of a mountain.

Mapping of historic spoil heaps is at its beginning that is why I 
started this discussion. And I would say70% of them I would map as a 
line, 30% as an area because its surroundings are clear. But even for 
the area type I would need a way to map the slope as not every spoil 
heap has steep slopes. Discussion was about started slopes, not about 
spoil heaps.
