Northern Plains ID help

[Hippy]

I picked up a few pieces recently that I dont know much about. It's a small collection from the Dakotas altough I dont know exactly where. I believe the top two brokes are Bijou Hills material. Does anyone recognize any of other materials? Also does anyone know of the type or material on the long, stemmed piece. I'm not sure but I was thinking the material might be Flint Hills Quartzite Thanks for any help that anyone can give me.

That long stemmed piece is exceptional and a center piece in any collection. I don't know what it would be typed as in the dakotas, but I would call it an Adena Dickson if found in the midwest.

The Bijou Hills will be a greenish color, at least every piece I have found and seen is. The bottom left piece looks like a segment of Sheet Chalcedony/ a piece of a Badlands Knife. Should be very flat both sides and about 1/4 thick. Dull crusty looking exterior with nice trtanslucent material showing at flaking?

We have a lot of glacial deposited rocks that were often used making id difficult, especially from pictures.
