Wayne County Michigan
Expert Response
Nice river rounded cobble. I suspect it's either limestone or dolomite, based on your images. Michigan has some amazing geology. Attached are two documents I found that show Wayne County. They are published by the Department of Natural Resources in Michigan and Wayne State University. The DNR would be a good resource to ask further questions about your rock. https://wmich.edu/sites/default/files/attachments/u263/2014/1987_Bedrock_Geology_Map.pdf
