Monty, Neanderthal and Thirty7, I appreciated your comments. Monty, you mentioned the gypsum deposits. One of my favorite places is an area known as "Antelope Hills". Indeed, these are 300 to 400' hills located on the 100' meridian between us and the Texas panhandle, with gypsum covering (I believe). Custer mentions this area several times in his books as important landmarks. Indeed, this was the turning point where he turned from south to east before he struck Black Kettle on the Washita in 1868. I recovered a Bronze US Cavalry rosette from that region. You're right about the topography. Just like our weather, if you don't like what you see, just be patient because you'll get a look at just about everything from one end of the state to the other.
Neanderthal, yes the piece is translucent, but because of its thickness, barely so. It's really a bit more attractive in hand, and if I can obtain a more lifelike photo, I'll post it. Thanks for the comments.
Thirty7, Yea, I couldn't believe the amount of flint. Typically, one has to really work for flint pieces. Here, it's a matter of sorting out the hundreds (or thousands) of flakes and cores. It's a nice problem to have, but it sure demands a different approach to differentiation. Again, I appreciate your comments.
