I meant it literally. It has snowed a handful of times here, but it
melts as soon as it touches the ground.

I put something together last night. I guess it looked like a blob mesh
would on a little isosurface mauntain range I made. That is, it looked
like white, puffy grass. The parse was about half an hour, but the
render time is measured in minutes, not days. I took a look at Gilles
website and saw that he had noticed the same problem, that the algorithm
only produces good results in small patches on tree limbs and such. I
built the mesh so that it can be further refined (within the limits of
fp precision) so the with enough memory, an acceptable snow might be
made on a jagged enough mountain. I would guess that mountains don't get
snow-covered in one pass anyway, so it might be that this algorithm
would never produce realistic results on a large object.

I set followups to p.gen if you have any further comment.
