My final day at AGU was Thursday, and I spent a lot of it working on school stuff, but I did zip down to the Moscone Center for a session on communicating science to the public in an age of increased public scrutiny.

Long-time readers (and students) know that I have a special corner of my heart reserved for plumose structure and hackle fringes, that finely-filigreed anatomy of a fracture surface. Fractures are everywhere in rocks, and often they show neat little “topographic” details that show fracture propagation direction and stress fields. Here are three that I haven’t yet posted* from more than a year ago, when I spent a week in the …
