Nice find. Shame about the tip.
Looks more Woodland to me. Been lots of confusion over the years between Santa Fe/Tallahassee. But Im guessing Woodland era. What other types you find there? Pottery shards in that field? Might help with typing this one.
Yes a lot of pottery shards in area. Ill try to post some pics later of other points ive found in the same area. I believe most of them to be bolens. Excuse my ignorance not exactly sure what you mean by the base being ground?
