As in this case, some yellow & red jasper can be extremely hard & difficult to #flintknap. The hardness means it makes great, long-lasting flake tools & drills. #Archaeology
Another lithic quarry piece from the Wetherington Island site (8HI473) near Tampa, Florida. I previously noted the Swiss cheese bedded chert/chalcedony in the creek. Here is a large chunk they removed & bashed as they looked for a usable piece to #flintknap. #archaeology#flintknapping#rocks
