Hey, I collect rocks from every holiday, but unfortunately I'm a complete novice and have no knowledge of rock at all, I found this with another strange few rocks from the grand canyon and the petrified Forrest, this rock was at the top of the grand canyon and has 3 holes filled with a glittering substance like quarts, there's nearly a 4 hole too, is it a natural rock? Or possibly some sort of fossil? I would be hugely grateful for any help!
