This area of the state falls within the Ridge and Valley physiographic province, characterized by elongated sequences of folded sedimentary rock. The Project corridor lies primarily in the valley between Great North Mountain to the east and South Branch Mountain to the west, within the Cacapon-Town watershed. Streams in this region typically follow a trellis drainage pattern. In the Ridge and Valley Province, long axes of the folds control the shapes and orientations of a series of long, narrow parallel ndges and intervening valleys. The differing degrees of resistance to erosion of the sandstones, shales, and carbonate rocks comprising the lithology deter'mine local relief. In general, the more resistant sandstones cap the ridgetops, protecting softer bedrock below from erosion; limestones and other carbonate rocks form the lowlands and valleys (Woodward, 1997). The Project corridor exhibits a range of topography, from the fiat floodplains of the Lost River Valley (1420 feat elevation) to ridges in excess of 2400 feat in Hardy County. Elevations within Hampshire County range from 1700 to 1860 feet. 6.1.2 Project Area Geology The Project corridor's surface geology traverses Upper Devonian strata, which grades from greenish shales to gray sandstones, and include gray sandy shales and conglomerates. ...
