I don't know if this works, but it's worth a try: 
you mention intersection two plains, did you try intersection the heightfield
with its negative? If you translate the negative up a bit I think what is left
is a cut out of the peaks. Translate this up a little bit to make it stick out
of the original heightfield and do some funny stuff with media.
What I would probably do is whack a blob on each peak (you already have the math
for that).

Good luck,
