Was looking through an old shoebox of artifacts at my grandmothers house this weekend...couple observations....
1) most were rhyolite....normal for this area
2) It's amazing how thin some of those old Hardaways were, must have been from small thin flakes, virtually no steps, minimal flake scars except the basic shape, and stupid thin for rhyolite and stupid thin for most anything else.
3) There were Indians that I could relate to
...there was a Guilford in there that was as this as it was wide.....1:1 probably.
4) Ive looked at those points a hundred times...but havent really looked since Ive known anything about the art.....more Indians I can relate to= STEP FRACTURES
5) While Ive only found 1 point that wasnt quartzite or rhyolite here, that shoe box had some slate points that appeared to have chipped away and then beveled. Also a two different broken points that appeared to be ??Burlington?? not sure, but was white, and not the weathered rhyolite cortex white, and possibly a couple agrillite (dark colored, similar to dark rhyolite, but no cortex??...apparently hard with steps and thinning issues as well) points.
6) Savannah rivers appear to have been the most popular, but not majority, with a wide variety of other styles.
7)
FINALLY....Rhyolite, my stone of choice to learn on, is not obsidian, it's not cooked TX, or anything else......it's TOUGH, IT WILL STEP and ROLL OUT, and even the guys who's lives depended on it couldnt make it look like James Parker, or even some of the points Alan and Lyman have posted, all the time, perfection will come, but there is nothing wrong with UGLY, STEP FRACTURED, slightly THICK, USEFUL points. Not really any point to this post, and pretty much a waste of 5 minutes, but I loved artifacts before, and now that I know a little (maybe can't reproduce them yet) about them, I love to go back and look at them and see where their troubles were as well.
