Hi Everybody, here is the story. About 4 years ago I acquired about 100 arrowheads from a scientist in California. To be exact Pacific Palisades. Locals used to tell me that they could find arrowheads quite easily on the hillside. Well I am not quite sure whether these are local or his special collection from many tribes. Please let me know your opinions. I will posting another 5 pictures in new topics. Let me know.

AA - Since we can only see one side of these points, I'm kinda doubting #1 and 4 in this pic. I don't see any edge work on them on this side. Number 4 appears to be more a base with a broken tip. Just my opinion.
