Summary:

In report area, consists of shale interbedded with massive conglomeratic sandstone. Commonly contains three conglomerate horizons in east--at base, in middle, and near top. Lower sandstone is highly fossiliferous, and upper one is very massive near Parkhead. Toward the west, sandstones grade laterally into shales that can scarcely be distinguished from overlying Woodmont shale. Underlies Chemung sandstone.
