I'm thinking that nobody has posted yet because they really don't know. I see what looks like a carved face, but at the same time I think maybe just a rock. That's Ok, because you are getting there and gaining experience. Now going slow is good, but you can speed it up a little by picturing an arrowhead in your mind. That's what you will be searching for. THEN, you will see other things too. Like this find, scrapers, broken points, knives and other artifacts. Also colorful minerals that you have there. Again, keep this find and after you have found more, you will know for sure. Here in central Texas we cheat. Big screen with legs, a shovel and the buckets of dirt go on the screen, sifted out and the arrowheads are left on the screen. I hate to hunt that way, but there are places here that charge you for the time spent. Tractor brings the dirt, you do the work. Hate that too. Have fun. I promise, you're getting there...
