In what part of the Country did you find it? If the field doesn't have similar size and shape stones put there by geological processes, then your round stone is probably an artifact or at least a manuport. Looks like a nice find ! HH[/QUOTE
It was found in northern Illinois the field has a lot of stones and boulders but nothing is like that one the research I have done suggests that there were Indians in that area up until the mid 1830 I was thinking some type of mano thanks for the info
