After returning to TBI from an exciting camping trip, we spent the afternoon relaxing and knapping! We used the raw material we had collected in the field: though everyone put their initials on the material collected, some students decided to share what they had collected (our students were so thoughtful, but whatever happened to survival of the fittest?).
Because we had a plethora of phonolite and limited rhyolite, Dr. Professor Harmand instructed the students to start with phonolite while they were “perfecting” their knapping skills. Phonolite (so named because of the clear metallic sound it produces when struck) can be a very good knapping material if it is fine-grained, and because phonolite cores can be rather large, allows for a large learning curve.
