Thanks Dale, I had fun tumbling those. They shine up really nicely, it just takes time to rough them in well.

They are nice looking pieces so.... It looks like you had no trouble breaking them up. That is hard material, teaches the patience factor. You can not rush flint.

The flint ridge is exceptional Rob. Wish there was a vein of it in every tumbler's backyard. I have found it in Georgia in the form of arrowheads in plowed fields, Native man imported it all the way to here. Easily a Mohs 7 rock perfect for tumbling. spiceman put you on some of the best.

Then they could be lakers. Lakers formed from volcanic activity over a billion years ago, probably in what is now southern Canada. Those volcanic deposits gradually weathered and released the agates. Glaciations, including the strong glaciation about 15,000 years ago, spread many of the lakers across the northern states of Minnesota, Wisconsin, Iowa and Michigan, as well as around Thunder Bay, Ontario. Wikipedia notes that "Lake Superior agates have been found in gravel deposits along the Mississippi River basin." I'm not super familiar with drainage patterns in that part of North America, but I think the glaciers could have pushed some of the agates into the northern reaches of the Mississippi drainage basin, where they could be carried south over time. Since the path of the Mississippi river has changed over time, your tributary could be where the main Miss. channel once was, which could be why you find them in a tributary of the Mississippi. So polish them up and make them shine like Jugglerguy's!! That's the plan. On a thread I posted under Slabs&Saws I posted a pic of a block I found and cut. It turned out to be Amethyst Sage. I find Amethyst in a lot of the stuff I find here. Found this today

I look back at this post just to see the ridge flint. Jugglerguy did a great job with it. The flint ridge show is getting closer. I've been saving my allowance. $
