I've done a little more research (although I still haven't been able to get to the local expert to ask what they really are). Apparently there was a quarry up above the (now) reservoir where I've been hunting, and I finally found the huge old and rusted cables associated with that quarry. I assume it was a greenstone quarry, as that is the dominant rock in that area. The first pic is a big chunk of both greenstone and milky quartz (or chalcedony?) with nice dark and medium teal/green fading into the quartz. The landscaping brick can be used as a size reference.
The next few are of various forms this stuff comes in. Some is (micro) crystalline kelly-green (epidote?) and some is typical dull greenstone with striations of other harder minerals which eventually remain as the softer greenstone wears away- leaving them raised in stripes or dots. With the normal river-tumble, these too eventually wear down leaving a striped or dotted rock. I think I'm finding red jasper up there too, but I don't think I have a pic of that. Ox-blood in hue. I'll have to get a pic next time I'm up there.
In the pic on the above right, the middle rock, interested in figuring out what the striated/grained inclusion is. Thought it might be scholr/black tourmaline, but now don't think it is.
