I forgot to post one more photo I took from the Craters of the Moon National Monument. I was hiking through lava formations that were adjacent to the camping ground and I came across this very strange sight:
This was taken in June!
At first I thought it might be the very strangest geocache I'd ever seen. No idea whatsoever. Anyway I thought I'd share the weirdness. I didn't touch it and left it to "weird-out" the next hiker.
