[QUOTE="Lefty, post: 291643, member: 2976"] Just got there today AR :lol: Was picking up [b]big[/b] rocks on Sunday, no need for specs then. But I've been putting it off too long, I've known for some time that my eyes aren't what they used to be. Had the eye test last week, just picked up my first ever pair of prescription glasses this arvo. BIG difference reading. I can still focus on small lettering without them but I have to squint to make it happen, they won't do it automatically anymore. Just finished a 2 carat green sapphire for a mate and wore the glasses while doing it, they definitely helped. No different when looking through the loupes but I don't use head loupes so having the glasses on made it easier. Cheers LGH, it was a nice big haul I go on Sunday. The area won't be there for much longer before they build a dam on the river and the gravel banks go under water so I'm making the most of the spot while I can. That's the biggest piece I've seen there Lone Wolf but there's smaller bits of the same stuff all over the place and some volcanic-looking bedrock in the secondary river bed (currently dry, main channel still flowing) have it over and around them as well - I think it might be volcanic. I think you might be bang [b]on[/b] the mark Shivan - there are lots of smaller bits with larger bits of gravel stuck together that look very, very similar to your photos. Waterworn gravel stones cemented together with what looks like some kind of obsidian. The books mention something in the area called "pitchstone", wonder if that's it? It sure looks like pitch or tar but is rock hard. [/QUOTE]
