almost devoid of bedding The sandstones are dark greenish in color are coarse of grain and while most is a fine conglomerate, the parcel beds with the pebbles up to 1/2 inch, though some coming around 1/4 inch, are in more or less widely separated grains. These pebble beds lie usually in thin sheets though at Times (towards the bottom) the whole grain is more or sandstones less conglomeratic. The pebbles are of fairly well rounded white (dominant) and pink vein quartz with scattering ones of pink feldspars. In places slate pebbles are common in green sandy slate in pieces up to 4 or 5 inches across and up to 1 1/2 inches thick. There are also small pieces of black shale. This shows considerable streaming action and yet there is almost no cross bedding. Only in places at the top of a thin bed is there a grain about 6 ft's wide, thick that is decidedly cross bedded and then are we away to the P.E. Evidences of foresetting type. The dip of the sandstones is about 30 deg to 45 deg.
