Found this along river bed in western Maine.....see a lot of white quartz but never anything like this.......would like to know more about this, thanks
Well it could be a cat, wear a priest hat. See the X at the bottom right of first picture . The large 7 above it. It's a nice find and your journey to find what it is referring will be a hard one.
itledo, to properly ID a rock, it would be a good idea to get a set of hardness rods. Then, need to be able to measure specific gravity and rock volume - both simple to do, but for the SG you will need a scale. Then with that knowledge, we can rule out lots of other stuff.
