And here as seen from Ullerntoppen!

Was leafing through some old pictures and feeling the need to share this one - it's a small outcrop from Southern Spain, basaltic-gabbroic rocks that have been metamorphosed. You can see the strong effect that the composition and texture of the initial rock has on the metamorphic product.

A small outcropping of rock with a rock hammer on top of it. The rock consists of three parts, a fine-grained grey rock (amphibolite) on the left, a speckled amphibolite on the right with large plagioclase and epidote grains, and a dark middle part containing large red garnets.

Thank you! You're right, I forgot to add them, but I also don't see an option to still do that now. Am I missing something?

I'm being told that there is a halo and a parhelic circle visible here. Very cool!

Apparently it's a circumhorizon arc
