Summer 2016 European GigaPan expedition: Sites wanted

Great news – I have been awarded a great professorship for the next two years. The Chancellor’s Commonwealth Professorship is a great honor and a major investment by the Virginia Community College System in me and my GigaPan project. I get course release time, a summer stipend, and reimbursable expenses of around $7500. I intend to use that money and that time to do a major GigaPan expedition in Europe …

Bedding/cleavage GigaPans at Harpers Ferry, WV

I’ve been thinking lately about Harpers Ferry, the spot where West Virginia, Virginia, and Maryland meet, at the confluence of the Potomac River and the Shenandoah River. I’ve noted small outcrops of its overturned beddding here previously, and also described a book I read about the man who made the place infamous: John Brown. I went out there again last week with my NOVA colleague Beth Doyle, and we explored …

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. (Other readers are encouraged to do the same!) Today, I’ll feature the first of them – though others will follow in weeks to come. That is crenulation cleavage …

Mirage, by Nina Burleigh

My latest audiobook consumed during my commute was the story of Napoleon Bonaparte’s (why do we always call him by his first name?) ill-fated expedition to Egypt in 1798. Napoleon brought with him a corps of “savants,” natural historians, engineers, artists, and musicians, charged with documenting the history and natural history of Egypt, and helping built structures and solve problems to make the colony work well. This was the expedition …

The New Market / Lincolnshire contact

Yesterday, I put a photo up here on the blog, and asked you to figure out where the formational contact was in that image. Here’s the image I showed you: It turns out that my plan to have readers upload their copies of the image didn’t work as well as I had planned – apparently you all don’t have as complete a suite of control options as I do. Shocker! …

Trace fossils in the Juniata and Tuscarora Formations

Route 33 in Pendleton County, West Virginia cuts across the lower Paleozoic stratigraphic section. I went there this past spring on a sedimentology and stratigraphy field trip with the GMU sed/strat class. The trip was orchestrated by professor Rick Diecchio. Here are some scenes from two of the stops – the upper Ordovician Juniata formation (red sandstones and shale intepreted as Taconian molasse) and the overlying Silurian Tuscarora Formation (thick …

Friday fold: cherts at Mount Diablo, California

My former student James O’Brien recently moved out to the left coast, and posted some photos earlier this week of a hike he took at Mount Diablo State Park in the mountains east of the San Francisco Bay area of California. There are some classic-looking Franciscan cherts exposed there, as these folded examples show: Seeing these pictures reminded me of the “GoSF” series I wrote last time I went to …
