I recently made a display for the local Jr College, showing Paleo and Solutrean style blades and points. I used various Texas Cherts just to give it some color differences. If FR would ever get out of the Stone Age and not require third party hosting I would share the pic’s.
BTW, was that your own work -- or photos of others' work?
Sadly, I had a nice supply of blue-gray Georgetown chert, and some good samples of various Edwards Plateau browns -- but it was in our garage in MA when we had a fire. Now, it's all heat-fractured... :-(
FReepMail for you...
