A return to coastal Italy on this wintry Friday… You’ll recall that The Other Callan shared some fold imagery with us a few weeks back as he explored the Cinque Terre region of Italy. He is back in the States now, and has been kind enough to share his geology-themed photos with me, so I can share them with you. Take a gander: Several people more familiar with these rocks …

Italy’s celebrated archaeological site of Pompeii is compared and contrasted with nearby Herculaneum in terms of art, architecture, visitor experience, and (of course) geology.

It’s the First Friday of Fall! Here’s a sort of fold to help you celebrate: a section through a ∧ shaped bend in a vesicular basalt flow from the eastern flanks of Mount Etna in Sicily. It’s due to volcanic lava flowing rather than ductile deformation of a pre-existing solid rock (our usual habit with this feature), but I think we can appreciate it regardless:
