Friday fold: Villa Romana di Casale
Okay, I’ll admit this is a bit of a stretch, but here’s your Friday fold: The mosaic-covered floor of this long hallway in the Villa Romana di Casale in central Sicily shows profound warping. The middle shadowed area sags downward by at least a meter, maybe more. It’s not a geological material that’s been deformed, … Read more
Friday folds: the Roman Forum
When in Rome, do Friday folds as the Romans do? Here are some images from my brief, sweltering visit to the Roman Forum(s) this past summer. The whole region is a jumblepile of ancient ruins in a thousand styles. Almost nothing is labeled. It looks like this: This particular building held up a bit better, … Read more
Building stones of the Acropolis (Athens, Greece)

But did you know there’s also a volcano there? 🙂 Here’s a shot of some snorkelers, with a lovely stack of pyroclastics rising up behind them.

Stone tools of the Piney Branch quarry, DC
Archaeology meets geology in this visit to the Piney Branch valley of Rock Creek Park in Washington, D.C. Cretaceous deposits of cobbles of Cambrian quartzite were quarried by Native Americans and modified into tools thanks to the fact that they break with a conchoidal fracture.
Vulture petroglyph from Castle Gardens, Wyoming
Happy new year! Time marches on – and here’s a reminder of times past… Check this out – a couple of what appear to be vultures, etched by native Americans into the siltstone at Castle Gardens, Wyoming: Diameter of the outer circle is probably 1.5 or 2 feet. My annotated (and generally embelished) version: I … Read more
Two Sisters
All this talk about footprints and tail traces, and I haven’t even shown you any “for sure” dinosaur fossils. Well, let’s remedy that today. We return now to the scene: exposures of the Jurassic Morrison Formation, on the east side of the Bighorn Basin, just north of Shell, Wyoming. I was wandering around, finding things … Read more
Pamukkale 4: Hierapolis
Atop the glorious pile of travertine that is Pamukkale (photos 1, 2, & 3), there is an ancient ruined city called Hierapolis. It was founded by the Romans in the second century BC, and was constructed (not surprisingly) from the most common locally available stone: travertine. A tomb with a view: This last one is … Read more
