This is a photo of a sandstone-filled channel cutting through some shale beds in an outcrop of the Mississippian Mauch Chunk Formation at Mile Marker 100 of the Pennsylvania Turnpike (I-70/76) in Somerset County. Photo taken January 3, 2000, facing south.
This is a photo of the Lower Paleozoic Wissahickon Formation in Fairmont Park, Philadelphia, PA, from the intersection of Bells Mill Rd. and Wissahickon Creek bike path. It is rather enigmatic to me, because the dark lenticular structures within the schist matrix are randomly oriented. This area is mapped as the Serpentinite Zone on the Germantown Geological Quadrangle map. The GPS coordinates are below if you are into metamorphic rocks and want to find this and look at it yourself - it's a nice bike ride at any rate.
