Was up in North central WI again over the weekend and found some more interesting (to me at least) rocks. Here's some pics. I think the first one is quartz with some iron staining but don't know what the black veins are, the second almost looks like a fossil but I don't think it is, prob quartz, and third is a colorful sediment rock of some kind. All were found in a wooded area near a small river/large stream that has abundant glacial til stones.
