Regenerating conifers on rough mounded waste rock
(slrpnk.net)
This reclamation is 10 years old and no soil was placed - these are going directly into waste rock. This is high elevation, so the trees grow slowly
Here is a little PDF on the method by the guy who developed it
here's a paper by him.

you can do rough mounding a couple ways; another way is to just have humps of topsoil, if you don't want to admix your soils, and it works pretty well. I've seen the results first hand.
We've seen this too, over here; they'll come in and eff up our sites, but it didn't happen here, probably because it's kind of in the middle of the mine.
