If a nursery sells plants, I'm wondering what a place that sells rocks is called. Something where they offer rocks of various sizes like this:
Well, those are all river rocks, but I'm wondering about for any rocks, even boulders or "slices" (or perhaps "slates"). In bulk/wholesale and retail. Perhaps a standard reference/source that has them would be nice but not necessary.
I am interested to know how rocks are harvested, what the process and distribution is and such.
