The rock formations of the plateau that cover the western part of the state are relatively flat, except on the east side where there are dominant folds and faults. These hold some of the oldest rocks of the region and range in age from late Ordovician up through the Mississippian. The rest of the Appalachian Plateau is of Pennsylvanian and Permian age and is where coal seams are located. The folded and thrusted rock of the plateau is made up mainly of marine sedimentary rock and volcanic rock. They are some of the oldest rocks in the world. In addition, much of this portion of the Plateau has deep bedded salt deposits nearly 50 feet thick. These deposits can be found some feet below the surface. It is estimated that there is enough salt in this area to supply the needs of our nation for nearly 2000 more years.

Specifically Chestnut Ridge Anticline, Coopers Rock in West Virginia, and Youghiogheny River area of Ohiopyle, Pennsylvania. Chestnut Ridge Anticline/Coopers Rock INTRODUCTION OVERVIEW The geology of West Virginia was first investigated in the mid late 1700’s to early 1800’s. The first official research was conducted my geologist William Barton Roger from Geological mapping was established by Israel Charles White between and is still used 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 age shale and Pennsylvanian age clay that is 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 lies 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, made up of small, white quartz pebbles, to red and green shale, to gray, very sandy limestone. The youngest rocks in the area 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 Cheat River cuts through the lofty Chestnut Ridge anticline which 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.
