Ok while the subject matter may be unappealing it got me to thinking (and thats never good). Native Americans have left artifacts called Discoidal’s and it’s always been assumed just like the link shows that they were gaming pieces. While I’ve never found a Discoidal on the ranch I have found hundreds of oblong very smooth stones that very in length from 4-6 inches, widths of 2-4 inches with thickness of 3/4 to 1 1/2 inches. First I assumed they were hammer stones yet they show no signs of impact, then I thought maybe they were used for indirect percussion. This has made me rethink their purpose and the reason their always found in old camp sites.

If we say they were used for cleaning the back side then that explains allot of what I’m not seeing when I look at it as a tool. Their always polished smooth and all pretty much share the same shape. When your done doing your business you just rub it in the dirt and clean it off for the next use.
That’s an excellent observation!
