I haven't been on for a while, busy summer, but trying to catch up. That looks like some nice material. It kind of looks like a "kentucky horn stone", which is a very hard rock. I have been experimenting with heat treating some rock at my place, buried under a camp fire. Have you tried heat treating it ? How large are the cobules that you are finding? Unfortunately Maryland has a dearth of good rock, but maybe I can think of something else I can trade you, for some to experiment on. Are you interested in some remade hunting points?
Best Regards

I wouldn't heat whole cobbles, if there is any water in them they'll crack and shatter or you'll get over cooked and under cooked rock in the same piece. Break them into spalls, and knock off some of the cortex if it's limestone.
You can do larger flakes in your oven, just put them in a baking pan and cover them with sand. The sand helps bring them up to temp slow, and take them down slow. I heard one of the Ohio Knappers cooks them on his gas grill (fills an old cast iron skillet with sand and flakes, and let's it go for hours and hours.) Easier to control temps, which on material like flintridge can help bring out specific colors, or so I've heard (and it's probably easier than digging a burn pit in your yard and keeping it stoked.)
I'd love to come get some of this been hunting for good hillsdale source since I started knapping last year. If u could help me with this and point me right it would so much helpReally pretty stuff that works well. Any of you knappers want to trade some materials pm me. I've got access to a mountain of this stuff.
