Besides the coal fragments, the basal part of the sandstone contains lenses of conglomerate bearing limestone pebbles and, in places, shows hard, concretionlike masses of cemented sandstone two to five feet or more in width. The basal sandstone rests on a gray-blue clay shale, probably a member of the Stranger formation, which, at the exposure examined, is considerably crumpled (figure 2).Character . . .
