It usually forms a bed in the three branches of the Eio Hondo and has in large measure determined the fall of these streams. Hard gneissic schists are interbedded in this conglomerate with occasional quartz. These rocks rest on faulted and folded, highly metamorphosed, reddish sandstones, shales, and schists of late Paleozoic or Triassic age. Overlying the conglomerate are about 75 feet of limestones with inter- calated shales. These limestones vary from 4 to 6, to 12 inches in thickness, are black, brownish black, weathering blue and, in eroded.
