197 August 29 - 1918. North Arm. Duntars outcrops are as follows:- Campied at a Herring Factory in the more gaur northern of the by Tates slope about 1/2 mile from the head of the arm on the north chine. Duntar and Edwards climbed the mountain that afternoon, and got the next day in a fog and rain Saturday (31) morning. Tyrrell over of but met me on the 30th. As we climbed up the mountain one more in a heavy Talus up to an altitude of about 600 feet, where one came to a nearly vertical face of bedded sediments about 20 feet high. These beds are much attuned to a mica-schist(?) and they dip at an angle of 25° or so into the mountain beneath the cliver gather of which they form the floor. The relations here shown in the east grade of the valley are as follows:- [Drawing] Dr. Tyrrell suggests that if the igneous material lies upon the sediments it cannot be the cause of their warping and disturbance. He believes the injection may be a result of the deformation rather than the cause. The highlands to the north of North Arm are made of the Cliver gather over-lift which rise in a step fold ocaps the highland or nearly flat table-land which has an elevation of about 2000 feet and is part of the old foreplain
