I would love to see some NJ finds.  I think the point that I have to the right of my favorite rounded scraper might be argillite.  I really never thought it was flint, but was unsure of the material.

I'm glad to hear that the weather is nice where you are too. 67 and sunny here. It's been a long time since we have seen that. What you said in regard to grooved axes makes a lot of sense. I never thought of it that way. I'd probably be surprised to find out how many farmers in this area have them. I showed a good sized stone artifact to a farmer one time that I assume was used  to grind nuts, seeds etc. and he said " heck, I've got two of them". Until I found it, I'd never seen one before. I guess I could always get a part time job picking rocks this spring. Then again, maybe I'll stick with hunting. Thank's jp.
