The long ridge trending N.W. from 1.55/1 into 1.4/5 is composed in part of a thick mass of highly amygdaloidal trap with the augddules commonly concentrated into bunches. Southeast of the road the trap exhibit well marked flow breccia structure. Over this trap (to the N.E.) and separated from it by a valley like depression 75- 100 yards wide is a gray playdate porphyry tuff which may be followed from the Pembroke-Dempsville road S.E. to the Penamaguen river near Small's Island. The interval between the porphyry tuff & the amygdal- oridal trap shows exposures only in 1.55/1 A where S.E. of the road the rock is a very massive basic tuff with residual pumice fragments while N.W. of the road the basic materials show sluire bedding into gray shales. These gray shaly-basic tufts contain fossils = Platyschisma common PMurchisonia (Forrotoma) comm. Bellerophon 3-lobatus occasional " "var. acutus rare Stenoscisma sp. occasional (w/o with gastri).
