Hey everybody, my dad emailed this to me and asked that I post it on here to see if anybody could help him identify these objects... as follows... A friend of mine was out hunting by Monte Carlo Road the other side of Ashfork (east), AZ, and he found these spheres. They range from maybe 3/8” diameter up to ¾” diameter and they are kind of greasy grey/dark grey/black. They are hollow and you can crush them. If you rub them across a piece of paper, they leave a grey streak, like graphite or carbon. Since I was taking Geology at the time, I took a half dozen or so in to my teacher, Beth. Well, they baffled her, she did not have a clue. We were guessing meteorite, tektites, lightning strike (fulgurites) all sorts of crazy things. So we decided to give them to the chemistry lab and see if they couldn’t deduce what they were made of. They are still working on that. BUT! Someone in the lab remembered walking along the railroad tracks when they were young, back in Maryland and they used to pick them up and use them for slingshot ammo. These things turn whatever touches them black, so I bet his slingshot pocket was black. Well, I searched all over the internet, but I must not be choosing the right words to search for. And the BNSF does run sort of through that area by Ashfork. So, now you know my quandary, do you perchance have an answer?
