Yep, aluminum nuggets from campfires.... much easier to put in the pouch than ones that look like they have been cut up with a mower....
Great lakes have a few ton of them along the shores in spots....
No just found it yesterday...no rock shops for 1000 miles....looks like one tho...if it was heavy I would think meteorite and if I could dent it I would think metal...mystery
Test it with a magnet, scratch it with something hard like a knife blade that will tell you if it is harder or softer than carbon steel/ss steel. Odds are, you will find it is light weight and aluminum, sometimes I found a few that would be slightly attracted to a magnet and the best I could guess was that something else melted with it to give it a slightly heavier weight and the magnet attraction.... I don't think you will find that it is anything valuable.
Whatever lol I know its not alum the right item is an alum nugget...left item cant be marked with a knife and the brown spot is where I hit it with a sledge and I cant mark it...Ill have to hang on to it
I spent 15 years forging aluminum pistons for a variety of engine companies, trust me, aluminum can be made as hard as a rock or a soft as butter. Just because it's aluminum doesn't mean that it can cut or scratch easily.
