8 Heresy's Cove. On the river road A Hersey's Cove where the road near the from 2:415 up to 2:416, at the lower end of the N.W. side of the road in eastern 2:417, the gray plantery striking out into the S.W. side and as a end by a large mass of galbros = 1183. This point marks the place where the ground bluff turns to the gray shale and shales begin to appear. In the rock face on the east side of the house, slaty shale contains flint-poor planerysts and this may be the equivalent of 1:574, but it is not certain that the rock is in place. The galbros crops out at the road corner on the east side 2:416, and again at the point on the road where Hersey's Cove is 2:427. On the north shore of this point the gray plantery strikes up and striking N. 19° W and dipping N.E. at a low angle. A Mr. Jackson's claim on a 10 foot ledge of the Blanchard shale about 100 yards N. of the point contains a few undetermined fossils = 2:427A On the south side of the large rounded point, 2:419 in the N.W. part of Hersey's Cove the gray shales disappear with the same strike and dip, strike N. W.S.W., dip 15° N.E. The shales can contain a few specimens of Grammysia exigula = 2:419A About the N.W. side of this point at SW. 2:416 the gray shales appears with S. strike of N. 70° W and a dip of 50° N.E. They are underlaid by a trap intrusion. The trap near the contact is about 18 feet firm contact, S. 130° E.S.W. 2:416A. The contact at NW. A large mass of green B on the shale shales contain Alcyodemia abundant Desmatites occasional = 2:416A On the west side of the N.W. cove of Hersey's Cove, the gray shales appear in couple of ridges in the N.W. corner but beginning this west of 2:427 A. This shore is formed by a mass of galbros with very large flinty planerysts, approximately the same rocks as 1:583. A specimen in 1:583. The rock may be a silicose porphyry. Returning this point on both east and west side of Hersey's Cove at N.E. 2:427 we find about 15 feet off the shore forming the edge of galbros of the same dipping with the gray shales near to the point, which in trap. 1:60°N.W. few feet from the contact and the underlying shale the trap as many planters. In the accompanying sketched map of the east side of Hersey's Cove at the point (A), purple red shale crop out striking N. 39° W and dipping 19° to the N.E. The purple shales lines contain scales with flint pieces, Alcyodemia (not collected) = 2:427A (B) the purple red shales strike N. 50° W and dip just and at C the shale strikes for a long distance. 9 as N. 20° E. and dip 17½° S. 20° S. Five fossils occur here consisting of pieces of Alcyodemia growing in the shell. Other fossils included are: Atrypa, Spirellida, Grammysia exigula, and a Crinoidite. The fauna is 2:428A In Figs A at the point (B) the strike of the purple shales is N. 40° W and dip 19° E. Here appear traces of a distinct fault between B & C, the panel trending approximately N. x S. 5 to 10°. In the southwest corner of Hersey's Cove on the east side in 2:523 occurs a patch of conglomerate and purple shales striking N. 84° W and dipping to the north at an angle of 19½°. The purple shale at this line display the strike & dip quite well, and are very fossiliferous, among them being: Phyllostromo (rare in 2:523 A) abundant Lepidocia (abundant), Beyrichia (common). Grammysia, Heptadomai perbrookensis Bill. (rare). The fauna is 2:52-3A. Also shale dip under some silicified shales & conglomerates similar to those on the east side of Hersey's Point, about three feet at one place large ladders of purple clay shale bed are common though not observed in place and suggest rock similar to that seen at a railroad on the highway in western 2:514 (east of Berry).
