I thought I did, but you could be right and I don't know. Maybe someone here can correct me if I am wrong. Below is the only piece I have picked up that I was told was chert. Isnt it usually grey like shale, but glossy and fractures like flint and obsidian? I have been told it's not plentiful in North Dakota. Some can be found along North Dakotas largest esker in Grand Forks county.Do you know the difference between chert and granite ?
That sure looks like chert to me , I have a couple that I think is grey chert that looks like shale but harder than shale that looks like it has been worked .I thought I did, but you could be right and I don't know.

Sentinel Butte has chert. Some years back a cache of about 100 Clovis points was found not far away and the chert was a match.I thought I did, but you could be right and I don't know.

Definitely a rock as I can see at least a couple of different minerals in it. And it sure looks like it's been worked. That might be an interesting one to take to an archeologist, mostly because if I use my imagination, I think I might be looking at a face.
No I haven't, not many around that seem interested in it as to it's origin.Have you dug up any information on this trapper ?
I would suggest the rock is in the shape you found it from rolling around under a glacier on its trip south from northern Canada. The reason there's a rim on it is because it's a softer layer of rock in-between harder rock/mineral. Seeing wear to the extent you have on that rock is not especially common, but it does happen. The key here is that "worked" rocks generally aren't as irregular in the workmanship. At least, that's the way I interpret it.No I haven't, not many around that seem interested in it as to it's origin.
