This outcrop is located along the newly constructed portions of West Virginia Route 55 (Corridor H) west of the town of Moorefield. These folded beds are in the upper Silurian Tonoloway Formation. The Tonoloway Formation is a 400-600 foot package of gray, medium to thick bedded limestone and dolomitic limestone with tan shale and minor amounts of thinly bedded sandstone. This unit is interpreted as a Devonian tidal flat environment with mud-cracks and halite salt casts. Well developed halite salt casts can be found in several of the weathered shale intervals. For a closer look at these Halite clasts see this macro gigapan http://gigapan.com/gigapans/142740 Geologists interpret this period in earth history as time of tectonic peace during the middle of the paleozoic. These passive margin sediments were originally deposited horizontally during the Silurian lithified and then folded during a the Alleghanian Orogeny in the Pennsylvanian - Permian.
