After reading Mika McKinnon‘s endorsement of this series on Twitter (example), I downloaded an audiobook copy of N.K. Jemisin’s first book in her “Broken Earth” trilogy, The Fifth Season. It is a fantasy novel with a healthy seasoning (ha! no pun intended) of science fiction. The story is set in a world called “Earth,” but … Read more
A solo hike in search of anticlines yields new outcrops and good views!
Snow may have cancelled the geology class, but there’s plenty to see outside! Join us for a tour of three fine examples of physical analogues in snow that show deformation akin to that we observe in rocks under tectonic stresses.
Today’s Friday fold comes to your eyeballs courtesy of my colleague Shelley Jaye, who took it in 1982: She found this in a glacial moraine adjacent to Lovlibreen Glacier, on the north shore of St. Jonsfjorden, Spitsbergen, Svalbard. Very cool disharmonic folding. Thanks for sharing, Shelley! Happy Friday to all.
Last week, I was in Morgantown, West Virginia, to deliver a colloquium talk to the geology department at West Virginia University of geological visualization. The next day, I took some time on the way home to geologize a bit on the road called Corridor H, a gorgeous transect through the eastern Allegheny Plateau and western … Read more

Prum positions himself as a modern advocate for the ideas Charles Darwin expressed in The Descent of Man, and that Alfred … Read more
It’s Friday! Let’s head to Utah for a guest Friday fold photo – a river rat’s view of the Raplee Monocline!!
As noted previously, the old way of viewing gigapixel imagery is no more. But there is a new, better way. The GIGAmacro company has a better viewing platform that can be used either with images uploaded to their server or with pre-existing images that currently “live” at GigaPan.com. Here’s an example: a roadcut of limestone … Read more
The authors of this essential study are both scholars at Harvard University. They specialize in studying the decay of democratic governments and societies, one in century-ago Europe, and the other in half-century-ago years ago Latin America. They spell out the structure of authoritarian takeover across these different contexts, and then turn to our situation in … Read more
We return today to the scene of last week’s Friday fold, for it turns out that you can see some additional awesome folds from outer space (via Google Earth). Do not adjust your monitor: these patterns mean show up a stark and wavy reality!
