Friday fold: recumbent limestones of coastal Grosseto
Samuele Jæger Papeschi not only provided this week’s Friday fold, but he also serves as its sense of scale: According to Samuele, these are: folded metalimestones in Punta delle Rocchette, Grosseto. This are pretty interesting transected folds, showing about 10 degrees of foliation dip in respect to their axis Thanks for sharing, Samuele, and happy Friday, all!

Summer 2016 European GigaPan expedition: Sites wanted

Friday fold: Apennine crenulation cleavage
My new social media buddy Samuele Jæger Papeschi and I collaborated on some goofy maps in August, but then he noticed my Friday folds, and like the very best human beings anywhere, Samuele offered to pitch in with a few folds of his own.

The lip of the caldera
One last post from my September trip to Greece. Here’s a look north along the inside wall of the central caldera of Santorini, taken from the deck of the Santos Winery. It’s not hard to imagine the volcanic edifice that filled the space to the left (west) prior to The Big One.

When we went to Greece in September, we didn’t just look at …
