found in central Pa., pretty sure not fort payne, and positive not onondaga. These are the only pieces of this i ever seen in collections from around here. If these are common somewhere, then someone should have the answer, but maybe they are those rare lithics that every collection has and forever remains a mystery,
I see you find Dauphin County white.
Why wouldn't you think the lighter one was the same material? Might just have a little higher silica content in that particular vein looks like the same iron deposits
