This is a highly deformed section of the Devonian Foreknobs Formation exposed near Bergton, Virginia. The Foreknobs Formation (formerly known as the Chemung) is a mixed package of brownish red to grey sandstone, siltstone, shale, and minor conglomerate. This formation is part of the Catskill Delta, a shallowing upward sequence of marine clastic deposits which filled up the Devonian foredeep basin. These rocks were likely deformed during the Alleghenian Orogeny in the Permian.
