July 15—1918. Sunday. West Bay. After breakfast started south east around West Bay to the head into Piccadilly Bay. Car contains red film and black (fine) like they were from camp, much crushed and marked shales with them sometimes. They are of the oysterfaced series, and are probably ejected if from the profile. This is about 2½ miles south of Cape Horn where we came upon blue to black limestone shale and some concretely peeling limestones. One are for light chlorite clay. These strata are related with a peculiar profittile fauna that contain faunal elements of the Beadmontown and Hornawkill. Small Phyllopodites Tetraraphites, Haldymorphites and many other forms occur here. Also a Longina is common. Otherwise nothing. If this is of the Tate head series it is a different and seeming pelm fauna than this one. At the head that distinguishes West Bay from Piccadilly Bay occurs the Car Head Concretions. The man makes a left and side ridge and the thickness may be 500 feet or so. He could not measure it because no bedding can be seen. The Car Head concretions more shows bedding planes. The fragments are small under 1½ inches thick at times one sees piece up to 4 inches. No large masses occur here. All the fragments are of the Chepy and are angular. In Piccadilly Bay at the end of the Car Head cowl, we again came upon the Hornawkill proft-lite fauna but the fauna is far poor developed. Bring further into Piccadilly Bay, after an unrefined space one comes upon another up series of Car Head concretions. Here the fragments are also small but there are pieces up to 2 feet across. This second group must be faulted in to repeat the same succession as...
