Thanks folks-ptsofnc- It somewhat depends of the site. Woodland sites generally seem to have had better trade/access to rhyolite and other non- local materials along with some of the early archaic types. Almost all the Savannah River points around here are local quartz/shell/slate type materials. Guilfords/Stanlys/MM's are about the same but a few more rhyolite ones from time to time. Coastal Plains curt shows up here and there but not overly plentiful. ThanksYou've been busy. Nice finds/saves! Are most of your non quartz finds NC rhyolite? Do you some of allendale chert?
