MOUNT GRF.YLOCK. 167 



northwest from the summit, which cuts deeply into the central crest, and 

 which has already been referred to under Section G. This west dip is also 

 shown on Subsection H. The calcareous schist belt is crossed again and 

 recurs south in one of the forks of Groodell brook, in both cases with a 

 westerly dip. All this leads to the same interpretation as in Section G, 

 excepting that a small anticline seems to intervene here between the sum- 

 mit and the calcareous belt, the compressed syncline of the central crest 

 having in it a minor fold which does not appear on Section (i. 



The section then crosses Bald mountain. Here a great surface of the 

 lower schists is exposed. A high northeasterly dip is well determined at 

 locality 95 (see Fig. 41), and corroborated at locality '242 on the southwest 

 side of the mountain, both with a strike of north 40 east (see Case vn, p. 

 150); and an easterly dip recurs high up on the east side of Mount Prospect. 

 East of this locality the dip is east in places, but there are probably minor 

 folds and much thickening. On Section J, PI. xxi, which passes along the 

 south side of Bald mountain about 500 feet below its summit, horizontal or 

 low west dips occur, striking with the much steeper dips of the top, and prob- 

 ably representing the lower and broader part of the Bald mountain syncline. 

 East of this, in the Goodell hollow ravines, there are high westerly dips. 

 These facts, and the situation of the calcareous belt in the Hopper, have 

 rendered necessary the peculiar construction seen in the section. Bald 

 mountain thus consists on the east of a sharp anticline turned over to the 

 east, followed on the west by a syncline which probably consists of minor 

 folds. 



West of Bald mountain, along the spur between the line of the strike 

 of locality 242, on the east, and localities 106 and 645 (Hopper), on the 

 west, there is an anticline corresponding to the one at the top of Mount 

 Prospect followed westerly, between localities 218 and 217, by a syncline 

 corresponding to that on the west face of Prospect. West of this again, 

 between localities 117 and 217, such a succession of westerly dips occurs 

 that it has been necessary to insert a conjectural compressed syncline ami 

 anticline in order to explain the dips as well as the absence of the lower 

 limestone. From the dips in the limestone and schist in the Hopper on the 

 northern side of the spur it is probable that another small anticline occurs
