Re: Odd's And End's
Okay, you have me confused now. By scientific observations I mean evidence- tell me why you have any reason to believe these rocks are anything. My "opinions" are based on evidence, physical, tangible evidence. Also from experience.
Now if I post pictures of my artifacts, which I have many times, I can point out a long list of things (besides it being obvious) of why they are, they all show signs, they show scratches, chips, abrasions, etc. Yours are based on... because you think so. That just doesn't work.\
You can't prove these rocks are artifacts because to be blunt, they are NOT artifacts... except perhaps that Quartz as it does look like there might be some flaking scars on the edge and it was a common material to make points/blades from.
I am NOT trying to convince you that the only artifacts left behind after thousands of years of Native Americans living here are polished stone and finely chipped stone artifacts... but I will try to convince you that very nearly all artifacts that have been altered in one form or another (accounts for about 98% of the total) will show signs of having been worked. Now if a Native picked up a random rock and threw it at a bird I suppose in some abstract way it would be an artifact and wouldn't show any signs of use... but artifacts in the traditional sense...like the type you mention, pestles, knives, etc... are easy to tell apart from regular rocks because there are obvious signs of them being altered. The rocks you have posted here don't have any obvious signs of being altered, they are a pestle or knife or whatever simply because you say so with nothing for evidence. I'm not trying to be rude or fight with you at all bean, I like you, I like having you on here as a very active member of the forum, I hope you don't get mad at me for all this but at the same time I don't want to watch the spread of missinformation and not step in. There could be somebody new to the hobby see your post of "artifacts" and get started on the wrong foot right off the bat.
