Here’s what the Sideling Hill road cut looked like last month:
It’s a terrific example of a syncline. Usually I show folds in profile view, but here, the view is essentially perpendicular (not parallel) to the axis of the fold:
Sideling Hill’s rocks are early Mississippian in age, made of debris shed off the late Devonian Acadian Orogeny, and they were folded during Alleghanian deformation in the Pennsylvanian-Permian.
Sideling Hill was my second favorite field site in college, aside from my two week field camp mapping in Death Valley. Thanks for the quick trip down memory lane1
I frequently pass through the Sideling Hill area on my way back to visit my family in PA. Thanks for giving me some ideas on things to be looking out for on my drive!
