Viewed from Frederick County (Opequon Creek is the dividing line), you can see strata of the Ordovician-aged Edinburg Formation limestones and shales. These anticlines and synclines formed during Alleghanian mountain-building in the late Paleozoic. Another set of folds is just upstream: https://viewer.gigamacro.com/view/1iUNiXJTWyLXTqWn These outcrops are on private property. Access was courtesy of landowners Jim & Rebekah Wiedower.
