Braved the cold yesterday and wanted to see what the rain washed up. Found a couple broken points. Some hammer stones? The last one I have no clue. Three evenly spaced small holes and one large in the middle. Thoughts?
Besides the three chipped stone pieces all I see are natural stones.
The triangle piece to the left is in shadow and hard to see but it looks like it may be complete.
That "spike" is interesting maybe a perforator or a type of drill.
The item in the third/fourth photo does look like a broken mano, but hard to tell without a hands on examination. Your last item is just a natural rock oddity. As for the items in the fifth photo, it look like you may have the tips of two points and you may want to share some more pictures of the center piece.
