Pisoids in the Ordovician Epler Formation

Pisoids in a boulder of Epler Fm excavated from a construction project that Geo-Technology Associates, Inc. (GTA) is consulting on in Cumberland County, near Dickinson, PA. Note the concretionary texture on the left side, where the rock has been fractured.

Photographer: Andrew J. Zmoda, P.G., P.E., works with Geo- Technology Associates, Inc. (GTA). He earned BS at SUNY Cortland, MS at UNC Chapel Hill in 1987. He earned his first PG license in 1991 in Virginia, second PG in 1995 in Pennsylvania, then his PE license in 2006 (Maryland and later in PA). His favorite geologic activities are field mapping and subsurface interpretation of strata.

Reverse fault and drag folding in the Pennsylvanian Llewellyn

Reverse fault with drag folding exposed during the excavation of material at the H&K Group, Inc., Hazleton Materials aggregate quarry. The fault plane that cuts through the Pennsylvanian Llewellyn Formation is highlighted here by the inclusion of coal from the folded and overturned Buck Mountain coal seam located in the footwall approximately 100’ below this elevation. This quarry is located one mile east of Eckley Miner’s Village, the downdip direction of the fault plane is approximately 170˚, and the photo coordinates are: 40.99607, -75.83986. Sadly, the gentleman at the top of the photo is drilling blast holes and the exposure shown here was gone within a week.

Photographers: Susan K. Brown, P.G., and Mark Eschbacher, P.G. Susan Brown earned her BS at Bloomsburg University, then worked 21 years in both geotechnical and quarry mining fields in Pennsylvania after earning her BS at Bloomsburg University. She loves the visual aesthetic and challenge of structural geology. Mark Eschbacher is a project geologist with H&K Group’s Engineering & Environmental Services Division with 40 years of experience after earning his BS at University of Missouri – Columbia (and State Fair Community College-Sedalia, Missouri). He credits Professor Rheta Smith at State Fair Community College as one of his inspirations for becoming a geologist. (Isn’t it great how we each can become inspirations for others simply by being interested and actively engaged?)

Anticline-syncline on Route 322

Anticline-syncline sequence in trace fossil-rich Lower Silurian sandstones exposed at a roadcut along Route 322 in Pennsyl- vania approximately 39 miles south of State College and ap- proximately two miles northwest of Arch Rock Road. The expo- sure overlooks the Juniata River near the village of Macedonia.

Photographer: Chris Mulry, P.G., currently works with Groundwa- ter & Environmental Services, Inc. He’s been practicing geology for 36 years after completing his BS at University of Delaware (including field camp in the Black Hills and parts of Wyoming and Montana) and then his MS at University of Maine doing field mapping and Appalachian structural synthesis. He likes both structural geology and geomorphology and yearns to return to Beartooth Pass southwest of Red Lodge in Montana.
