and dip N. 25° E. about 20° base Limestone occurs by a thin one foot to two foot and dips of a very light color and which is amygdala tized in places. This dike =1087 first and forks in nearly all directions. Within not far 15 feet of the gallo dike, the acid dikes fork but the forks do not pass through the gallo nor as they parallel in the other (S.E.) side of the gallo. Between elzabeta and the acid there is a thinned limestone gap of 10 feet which is not penetrated at the surface by the and so that it is impossible to ascertain here whether the and intrudes the gallo or vice versa. The gallo however distinctly cuts across the path of the and. On the east side of the little core of the head of the promontory in 6-24-5 there occurs a two foot vein (C) of dark gray nearly blackish coarse grounded rock which effervesces strongly under acid. It is markedly different from the surrounding limestones in texture & durability besides green color and appears to be a volcanic sill. It is annularly subhorizontal vertically, and with fine angular porphyryte in the lower 6 inches. This rock 1088 is most distinctly cut through by THE and schistone 1087. (See map). The western point forming the promontory in 6-24-5 is composed of the porphyry 1089. This porphyry has a very light gray magma and in places has few phenocrysts. One such specimen is 1090, without phenocrysts. THE PORPHYRY IS DISTINCTLY CUT BY! AND INCLUDES A 2-6 FOOT GABBRO DIKE which is almost entirely amygdala tized (amydulas less than 1/8 inch and which also has a few scattered felspars rather 1 to 2 centimeters long. The dike 1091 is nearly vertical and bears in general N.55° W. The porphyry, in 50 feet wide and on the gabbro side (forward) for a couple of feet along the contact becomes finely amygdaloidal losing the porphyritic character. This contact porphyry is 1090 B and recept for the normal amydulas is similar to 1090. The limestone on the west of the contact is intensely brecciated for a couple of feet. The and porphyry is opposite the main body from which THE dike 1088 was shot off: The limestones to the east are thick bedded with strike N.5°-W. dip N.E. with angular beds, & large masses within the porphyry about 20°. They are cut by a normal gallo dikes in the little creek and to the west of this dikes there is done with general varied dips varying from striking N.S. & west dips to strike N. 80° W. and dips N.30 and dipping N.60° S. These limestones include massive 3 foot layer of coarse grounded dark effervescent rock with obtrusive structure similar to and apparently the same as 1088, which appears to rise over the core of porphyry & this continuous with 1088. This side is our climb in the TP. This area of gallo makes a fault of over 50 feet extending N.12° W. and quite (1/4 mile or more).
