Found in Jackson County Missouri (I didn't find it myself, but I can most likely get more info on location it was found.) I do believe it was found in a dirt road alley.
Long dark grey and brown striations, that cannot be scratched with my nail. Then on one side in a few large chunks, an orange/brown (rust colored) residue, that can be scratched off.
I thought my pictures were going to look much better than this. So I can get better pictures ASAP if need be.
Let me know any other information I need to provide. Thank you for looking!
Hope everyone is safe and healthy out there!
