Field walk today

Found a few larger pieces of flint this time. I found the blob bottle top too and left it in photo to show scale.
2 pieces have the potential of showing some sign of human working, but not conclusive IMO.
Hopefully I’ll creek walk tomorrow. Thanks for looking.👍🏼

All of those look worked to me. I’m really surprised you’re not finding nearly finished bifaces that failed and broke in half. The knappers at your spot must have been really skilled not to break anything!
