WAAAAHOOO, those fur trade relics and Spanish silver are AMAZING! I would love to dig some relics like that. You and Dale (IA) know how to hunt for those early fur trade relics!
Now, get back out there and find us some more of those buggards!
As for the trade beads how are you finding them ? On top of the ground ?
At first we found ours on top of sifted fireplace dirt , but afterwards we'd haul bucket after bucket to the river and swish the dirt in a fine mesh spaghetti strainer , some buckets you'd get 40 or 50 beads , other buckets sometimes only 10. We sifted roughly 1 ton of dirt and theres still about 3 tons left to do. There'd be other "things" to find while sifting , like wampum , pins , and even several human teeth !
