Looks like you found some nice pieces. Not much for story telling huh? I've never found anything like that 2nd pic. A type of scraper? Last pic has some nice stuff too, but not the clearest pic. Nice artifacts.
I've found a good many pieces like the 2nd picture, i figure they are scrapers use to make cordage, your find like most of mine displays the profile of a native american's face!
Ya i see how the profile could look like a face, creepy! And idk just some sort of cutting tool came to mind, would easily cut cordage or help clean a hide
