On the tan one I was told it was probably a spall something they flaked off to use later for making a point or tool. It is a big flake I do know that. 1st spall for me Thanks for the replies
Flake, Spall, same thing.
Not really. A Flake by definition isn't really and artifact, it's just waste material. A Spall however is an artifact and in fact is what the flakes are driven off off for possible use. You can clearly see where large flakes were driven off of that large Spall and you can see it's been in the creek for quite some time.
good find. Find a flint knapper in your area and have him make you a point out of that tan rock.
