Thunderegg

[Rockranger]

Black rock thunderegg from Nevada. I posted this years ago on the old forum and cut it open recently.

That's a really interesting one, Rock. I love the fact that thundereggs look like junk until you cut them open to see the beauty hidden inside. I think of them kind of like Tootsie Roll pops with the surprise on the inside.
