These are all personal finds from North Alabama: Madison, Morgan & Limestone counties. I also hunt in some southern TN counties but not as often.
Many of these points were made long before we even knew what tribes were in North America. I guess you could say that the Mississippian, Woodland, and Historic periods had 'tribes'. In and around North Alabama that would be Choctaw, Chickasaw, Cherokee & Creek. These folks might take over another tribe, some tribes died out, consumed by other tribes, who knows...
The Archaic and Paleo arrowheads are very old.. 8000 to 12,000 years ago. They hunted mastodon, mammoth, giant sloth with these points. They think they crossed over from Siberia thru Alaska and into the US when the glaciers receded. They were Asian (Huns maybe?). There are other theories. Heck I can't explain it all... go here and listen/learn from the professionals...

Interesting stuff.
Here are some of my oldest finds. The older they are the more value they have to the collector.
The older points are the best made points. It's strange... a 'reverse technology'. They longer they made points the worse they got at making them. Why did the technology start with the best and end with Woodland field clunker points? Going from a purely hunting society to a cultivating society prolly had a lot to do with it.
