I'd found (& hunted for) about 18 stone tools within a half-mile of the area where this item was found , mainly war adz , 'tomahawks' & clubs .
The majority of the items , except this posted tool & net weights , were all grooved for fixing to handles .
I donated them to the Blackhawk Museum which was about a mile or so away (I kept this and one tomahawk) .
No pictures from the sites .
The main site was a gathering point for many groups of tribes , during it's heyday .
A long island in the center of the Rock River , which was described to me (by an elder of the Sauk tribe , descendant of Cheif Black Hawk) as 'paradise' , is now a gravel pit .
I found most of the stone tools on the banks of this island , often in piles of topsoil dross , scraped off by the gravel-pit folks .
There's still a Pow-Wow every year , attended by tribe members who historically came there in the past .
Images of Cheif Black Hawk are below , one from a life-cast .
