The greenish splotches are the nickle mineraloid,
garnierite. Samples aren't trivial to find- that is, expect to spend some time looking and "getting an eye" for them, but neither are they terribly difficult to find. My main problem is that I don't see greens (or reds) very well, though in this case, the bright sunshine helped. And I was able to pick out bits that looked like the right texture and luster, and as if they *might* be green, and tote them over to Dana to get her opinion. That way, she began to be able to find bits on her own.
This is by no means an important or "should be known" geological resource, but it's rare, an oddball with an interesting story. And that goes a long way with me.
