Just Rocks from the Root River?

Found these on a gravel bar on the Root River east of Lanesboro, seem to have some flaking, but not sure it's just naturally occurring:

River tumbled Cherts. Natural for sure.

Like Grim says, natural..

Also agree with natural but can understand why you picked them up, especially the 1st one. I would check that area out more. Definitely material type used.

Thanks everyone, its what i figured, haven't found an arrowhead (or looked for one really) since i was a kid. Up-North lives just down the valley from me, so i know there's got to be some there for me and my daughter...lol
