All my artifacts are surface field finds, All come from with in a 1/4 mile of my house. Been hunting since I was seven, when my dad got my started. Love ground stone tools, I'm founder of NA ground stone artifacts tools and ID group on Facebook. I live in a glacial kame culture area in NE indiana and many of the tools and artifacts I find are from that period. My main hunting site I call the double knoll, 90% of my finds have came from those two glacial kame hills I hunt. So far this year I've hauled home 50+ Side by side 1000## loads of stone from the field. And cleaned, sorted and inspected every piece. I'm now studying utilized cobble tools and artifacts, and how there so easily overlooked. I'm big on ground stone identification uniformity throughout the different regions, and identification of tools with no names, but show use wear or pecking, grinding or flaking. Lots of utilitarian artifacts are overlooked because people see low monetary value, but the real value to everyone is historic. And will help us all learn to understand the natives daily lives.
