While taking a walk with my boys last eve, we decided to follow the creek home. I had to carry my 5 yr; old cuz he didn't want to get his shoes wet and one time I told him to climb on but we were going to keep our eyes out for an arrow head. I found a couple of pieces of heat treated chert, passed one in the creek then saw the very edge of this one. I could tell by the color and edge that it had been worked with, but could only see the edge. To say the least, we were all pleased, especially Papa. I'm pretty sure it is a local material, usually orangish/brown, but turns red when heated. Thanks for lookin, any info would be appreciated, dpg
