Friday August 12-1910 Bonne Bay. Left Dalys Cove at 6.30 A.M. for Bonne Bay. A dark day with rain on and off. At Green Point we saw a large and fine exposure of the conglomerate series striking parallel with the shore and the strata standing nearly vertical. About 400 feet of thickness are shown. Near there are then hidden grey to dark coloured limestones interbedded with more or less cherted shales. Interbedded occasionally are thin beds (6-12 feet) of typical conglomerate in all of the pieces are small although they may be nearly one-ton feet long and 3 to 4 inches thick. Andward gradually the limestones become less dominant and the shales are almost without limestone. In these upper beds there is an ocean sand then large (?) conglomerate. About 100 to 150 feet above the base are some considerable Dictyomena and the numerous Necr Oenocephalus. No other fossils were seen. The beds are considerably faulted, usually the throw is small but in one case it may have been as much as 150 feet. The strike is N.80 E., dips 74 S. There can be no doubt that these rocks belong to group 15 because of the presence of the characteristic conglomerate of the group. We take it that this over is in this division (?) the upper part) where the conglomerate gives way to regular bedded material as is the case to the east of Cove Head seen by Torinholde on Wednesday Aug 10, at Shallow Bay. There can be no doubt that Div. 15 changes much along the strike or that in one place conglomerate predominates and in others, and especially towards the top of this division, bedded clayey sediments that cannot be interpreted as falling in masses.
