Native American Mortar Grinding Stone?
May 10, 2020 · The entire stone is about 5 1/2" by 4" and the depression is about 1 1/8" almost perfectly round. Not a deep impression; perhaps 3/16". It's unfortunate that there are so many distracting marks from the farm disks. Found in Putnam County, Ohio on May 9, 2020. I'm a new member and I appreciate your acceptance.
