Thursday Aug 21, continued
A perfect day along the ridgips.
Beneath the falls train 350' beneath falls to Fishermans inclined plane. Taken about 100' more to Cragl (D). This makes the SS series betw. Crags (4) and (D) about 700' thick. Later out, at 1000
In Cragl (D) the pebbles are all smaller hardly any exceeding from inches. Nor are its pebbles, but vein quartz are common (I'm from one nick) along with lens of granite. The largest Boulder seen is 6 miles across. The horns seen and taken along are Catacysa leadit, Halysites, Stomatopora and Crelopina demplicate. This Cragl (D) makes a little head N of Fishermans plane and around which I could not get. Had to make a detour of one mile N. to St. Georges church and would track along shore, easy to do since all the prints are small due to thick redded SS. Cragl (D) appears not to exceed 400' thick.
Beneath Cragl (D) is more SS as above, but weathering more dull red than those. The upper zone without interbedded SL is about 150' thick. The lower chalky zone and weathering more red than any of the high beds in 30' thick up to fault. Exit at 350'
Then comes the unmistakable fault, onto the "Bona-venture" to the south and Barbe's s to N. See sketch opposite. It is as Goldring has it in diagram Fig. 1.
To the N of the Fault follows the green Barbe's SS series (according to its dip 70°N 80°E) and here it stands nearly vertical, at 70° dipping E while on the other side of the fault the "Bona-venture" dips S.E.
