Known as a dissected plateau, the rock formations of the plateau that cover the western part of the state are relatively flat, punctuated by occasional sharp relief. However, in the eastern region, folds and faults generally dominant the landscape, indicating the rise of the Valley and Ridge. These formations hold some of the oldest rocks in the area, ranging from the late Ordovician period through the Mississippian, an earlier subperiod of the Carboniferous.. The rest of the Appalachian Plateau hails from the Pennsylvanian and Permian periods and is where coal seams are located. The folded and thrust rock of the plateau is made up mainly of clastic, marine sedimentary and volcanic rock. They are some of the oldest rocks in the world. Much of the western portion of the plateau has deep bedded salt deposits nearly fifty feet thick. These deposits can be found from 5,000 to 9,000 feet below the surface. Interestingly, it had been estimated that there is enough salt in this area to supply the needs of the nation for nearly 2,000 more years. ABSTRACTLocations of Geological Interest Youghiogheny River, Ohiopyle, Pennsylvania Morgantown, West Virginia ACKNOWLEDGEMENTS AND REFERENCE We will introduce and discuss the geology and underlying lithology common to Monongalia County, West Virginia, and Fayette County, Pennsylvania. Specifically, the locations of Coopers Rock in West Virginia, the Chestnut Ridge Anticline, and Youghiogheny River area of Ohiopyle, Pennsylvania have been selected for individual study. Chestnut Ridge Anticline/Coopers Rock INTRODUCTION OVERVIEW The geology of West Virginia was first investigated in the mid to late 1700s and continued until the early 1800s. The first official research was conducted by geologist William Barton Roger from 1835 to 1842. Geological mapping was established by Israel Charles White beginning in 1906 until 1939 and his methods are still applied today. These maps and discoveries have allowed better definition of the coal areas, rock layers, paleontology, oil and gas fields, and mineral resources. Morgantown sits on large deposits of Ordovician shale and Pennsylvanian clay used in the production of pottery, bricks, and cement. But the largest geological resource for the town’s economy is coal. Below the Morgantown area lays the Pittsburgh Coal Seam holding the Upper Freeport and Upper Kittanning veins of coal. The Youghiogheny river area consists mostly of Pottsville sandstone while outlying areas are shale. The rock exposures and landscape of the area tell the story of sedimentation, deformation, and erosion that is typical of this part of the Appalachians. The oldest rocks are part of the Pottsville group and consist of brown, gray and reddish-colored sandstones and shale. Younger rocks range from light-gray conglomerates, and are made up of small, white quartz pebbles, red and green shale, and gray, very sandy limestone. The youngest rocks in the vicinity contain the coal seams and are economically important to the area. The cliffs are of hard sandstone known as griststone, and range from 10 to 30 feet high. The massive sandstone layer that forms Cooper's Rock -- the Upper Connoquenessing Sandstone -- is exposed where the Cheat River has sliced through the lofty Chestnut Ridge anticline. The ridge extends southwest from Pennsylvania across most of West Virginia. The sedimentary rocks of the surface were formed during the Mississippian and the Pennsylvanian periods. The other exposed rock layers mainly consist of sandstones, shale, and limestone. The processes responsible for the geological development of this particular Appalachian region are remarkable. The formation of the mountains and plateau was, and still is, the result of an intricate symphony of folding rock, tectonic activity, pressure, and vast expanses of time. Out of this 470 million-year-old progression, a diversity of minerals and natural resources arise and provide the region with a basis for a thriving economy. Driven by the powerful, timeless engine of the Earth, the Appalachians will always provide a fascinating geological record. http://www.ohiopyle.us// http://thevoltagegate.blogspot.com/2007_02_01_archive.html after West Virginia Geological Survey, 2002, and A Geologic Time Scale; Cambridge Earth Press, 1982 Photos by Angela Lands
