In the northwest corner of Broad Cove below the letter A in Eastport empty two levels strata (only one on map) which run in their center portion over generally straight dip-marks of fossiliferous shale. The strata are gray in color and rather coarse. The calcareous seams are very abundant, especially in the lower level which are from 1/4 inch to 1 1/4 inches thick. Generally an inch. They are full of fossils which are unfortunately unrecognizable. A few fragments were collected (-6.5-6a). The fauna includes a few orthoids, a modioloid (not collected) and a rare Liguula. The rocks strike W. 70° N. x E. 70° S. and dip at rather heavy angles - 66° in the lower gray (recently noticed in place) and 50° in the upper part, direction N. 70° E. Perhaps 30 ft. of strata are exposed.
Beginning just west of the little ravine (west of the middle of C.5-6, east of South of the letter E in Eastport, there is a series of long exposures of shales and calcareous seams, evidently of the same runs as the rocks including 6.5-6a above. The beds dip 45° direction N. 70° E., strike W. 40° N. by E. 70° S. The calcareous seams are here quite abundant, as in the preceding outcrops, & one calcareous band runs 5 circles thick. The gray shales resemble dirty beds in their fine grain & in the appearance of a network structure. The fossils contain some species of modiolopagoda. The calcareous layers mostly commence with k orthoids. A few thin bands of quartzitic sandstone usually finely banded, the fine bedding (stratification) showing cross bedding. A rare Liguula is scattered throughout the shales - a seam of modiolopagoda was collected. A muriciform - like gastropod in also present but very poorly preserved. Forms 6.5-6b.
About 25 ft from the east end may be seen another fault extending N. 20° W., not the east side gray & blue with about 4 feet, x entire depressed about 4 feet.
Showing contoller or seat (downthrown) side of fault.
Just west the west end of 6.5-6 (at the west end of the little arroyo, north gate of S & W shore line on map), the gray shales are followed by reddish purple beds which feel like red shale but are not without the slightest trace of fossils and which greatly represent purple volcanic flows: there are no foreign inclusions. At this point a thin one foot belt of light gray quartziferous rock cuts across both the gray shales & the purplish beds. This also dips about 45° N.E., trend, extends N. 10° E. x or [illegible] 1019. Twenty feet this west the purple beds so again cut by a dike. This dike is thicker about 10 ft. across and extends N. x S. 25 x 1019 dirty feet west is another thick dike which penetrates up into the gray shale but does not go through and the cross cuts up a white covered with shales & calcareous seams. That the latter
