Larson1951,
Hippy is right, they are novaculite and come from a cache of 223 points. As I understand it, these were from a couple of quivers that were piled together in a cache (leaving only the arrowheads all clumped together and pointed the same way.)
Here is a link to a similar type quiver cache found at Cahokia. I'd have a heart attack if came across a cache like that.
