Thanks for the nice words, gang.
NG, it's about 7" (~18 cm) from point to point. Tennessee, I'm not big on using the centimeter scale either, but I was gently admonished once by one of the OU archaeologists for not providing scale with my photos so I made a few and try to remember to toss them in. The piece came from up north of Arapaho, an area I rarely ever hunt. I noticed a few more of these on random sites on the internet which also came from northern Custer county. I typically hunt the western and southern edges of the county. Clinton, Oklahoma (my home town) is pretty much on the southern edge of Custer county. Alibates is very common in this area as the principal quarry is north of Amarillo, which is about three hours west of here (175 miles). Apparently, it was traded heavily in this area. I frequently hear from folks back east that they rarely ever see it. Any time you want a bowl full of it just let me know, and I'll cover you up in flakes and broken pieces. I do, however, think it is one of the more attractive materials. Josh and Jamey, thanks for your kind words. I've learned a little more about creek hunting, and hope to happen on to a few more pieces before harvest gets here.
