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:-

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
