looking for some info. is there a list of states that allow artifact digging?
Bottom line answer...NO....matter of fact not all States host artifact shows. Maybe 5 yrs ago I spent a couple hours hunting for advertised public dig sites,,, best I found was a PENNSYLVANIA land company that for a LOT of $ was offering people a chance to walk ( NOT dig ) on their Utah property.
The ancients have been proven to have been over every square inch of N America that was not under Ice or water...you just have to intensify your search in your local area
Best example...Ex Texan GTwn doing very nicely in Oregon.
