Can anyone ID these finds?

Found these three in a Northeast Missouri creek this past winter/spring. The farm they came off has produced a wide variety of points of various ages.

The larger crescent shaped on looks like it may be a knife to me. It is worked to a nice edge on both sides.

I am guessing the small pink one... must be a bird point?

I was also wondering if you folks think the small white one may be a Madison? You can just see some serration to the sides...the base is has a sharp edge similar to the sides.

Thanks,

Chris

Your little white triangle looks like the tip of a broken point salvaged into an arrowhead or dart point by thinning the base.

Your big one is definitely a Backed Bifacial Knife. The flat edge opposite the cutting edge allows downward pressure that's not hard on the hand exerting it. It's roughly one half of a preform/cache blade.

Now. What is the material it's made of ?

Uniface,

Thanks for the comments. I was thinking that the knife might be made of Burlington Chert...heat treated thus the orange color. I'm very much an amature at identification of artifacts and in id of various types of Chert. What do you think?? Burlington?

Looks like it, archer66.

But you're much closer to the source than I am
