And here's a spall(??) or core(??) my son found yesterday while riding through our field on the ranger. I could be wrong but I think it's the material called Starved Rock banded, similar to Utica banded or Oneota.

Nice variety of finds in a flint poor area. They used anything and everything that was chippable.

Smoky Hill Silicified Chalk

We find artifacts made of several distant lithic sources that are in my favorite materials category; however one of my favorite lithic materials is local. That lithic material is called Smoky Hill silicified chalk (SHSC) and is often referred to as jasper, commonly as Smoky Hill jasper.

These Nebraska and Kansas found Harahey Knives provide some color examples of the Smoky Hill jasper. The dark maroon example is Smoky Hill jasper that has changed color due to being exposed to high temperature. Smoky Hill jasper is rarely heat treated as it does not need to be for knapping. Interestingly, this knife was found within a lens of ash and I have no idea how or why it became exposed to high heat or fire.
