The Lock Haven Formation stretches across the state of Pennsylvania. Named after Lock Haven, Pennsylvania when first described in 1977 by Faills and Wells. The Formation was adopted by the United State Geological Survey, and assigned as one of the four formations to the Susquehanna Group. Replaces most of the wrongs formerly believed to be included in the Chemung formation (National Geologic Map Database). The Formation can be seen in Bradford, Blair, Cameron, Centre, Clinton, Lycoming, Mckean, Potter, Sullivan, Susquehanna, and Tioga County, Pennsylvania. The Lock Haven Formation underlies the Catskill Formation composed of primarily of gray to red sandstone and overlies the Brallier Formation composed of olive gray to dark thick laminated marine shale. Also the Lock Haven Formation is composed of Devonian aged (480 million years old)

The exposed rock material has a visible reverse fault, and is heavy faulted/folded. Visible soil, and vegetation growth on exposed section of the formation. Visible iron oxide staining from fractures in the section both natural, and manmade. Alternating material layers light grey to dark grey in the formation, and thick bands. 0 to 3feet of the section is composed of light grey, and soft material. The bottom facie was a small section of laminated layered shale. 3 feet to 6 feet of the exposed rock section fine to medium grained, dark grey rippled sandstone facie. The rippled sandstone may be contributed to the receding and progression of tides. The sandstone facie is cross-bedded. This layer contains some siltstone, and thin layer of conglomerate. Palo-environment of the Lock Haven formation is a warm environment, and ocean environment. Marine environment trace fossils; shell impressions. 10 feet to the top of the exposed formation is a mudstone facie. Top facies is covered by
