Local materials were used, and all points show some patination.Handbook of Alabama Archaeology: Part I Point Types|James W. Cambron
Patination is noticeable on all, and smoothed flake scars are not uncommon.
Patination was evident on all the basalt specimens, though not as heavy as on similar implements from a number of the other sites.
Many of the specimens exhibit a lesser degree of patination, though there are some that are heavily patinated.
Again, on all the basalt specimens the patination is very marked.
