Felicia provided two boxes, approximately 75 lbs total, of Texas flint nodules by way of Craig Ratzat/Neolithics.com, along with bags, instructions and note sheets.

The stone used for the experiment was nodular, fine-grained flint from Texas. Each nodule had a white cortex that needed to be removed by flaking to expose the flint inside. Cortex removal was a challenge for some of the nodules. The participants had varying degrees of difficulty detaching blades from the flint after cortex removal.

The object was to attempt to make blades from the flint nodules using 'abo' tools, i.e. soft and hard billets. For that we used elk and moose billets and locally-source hard sandstone hammerstones. We would then bag the blades, debitage and left-over cores for Felicia to analyze. Her analytical focus was to see if the skill of the knapper could be determined by from the core, blades and especially the debitage.
