115 Quadrille Ruled Form. Patented 1906. John C. Moore Corporation, Rochester, N. Y. 6.44 2/5 At the head of the core running north thru 6.44.5 into 6.44.2 occurs a series of exposures of fossiliferous shales overlying intruded rhyolite & underlying intrusive trap. The rhyolite is exposed on the west side of the core & is of a greenish & bright salmon pink color & exhibits beautiful flow line structures - Specimen 6.44.2 (1). The flow lines are very variable in strike & dip from point to point. The shales are exposed to best advantage at the head of the core on the east side. Strike N. 7° W, dip 48° A E. About 33 ft. are exposed here but the total thickness of shales to the trap intrusion on the east is probably over 200 ft. The shales are gray in color & are characterized by a vast abundance of Lamellibranchs. These occur in such profusion as to literally compose the bulk of the rock for thicknesses of as much as 2 feet. The lamellibranchs are of only 2 variable forms "(1) Grammysia, (2) a concentrically stratified (non-ribbed) Actinoptrella", or oblique, eared Pteronitella. The sediments are flanked on the east by the trap which forms a lovely escarpment in the east side of the core. Over
