DALY: GEOLOGY OF THE NORTHEAST COAST OF LABRADOR. 203 
mined at forty-four hundred feet in height. This peak is, so far as 
known, the highest yet measured in Labrador. The other peak was not 
climbed, but was estimated by these gentlemen to be fifty-three hundred 
feet in height. Still higher summits dominate these on both sides of 
Nachvak Bay. From Mt. Ford the writer saw two extremely sharp horns, 
bearing N. 25° W. These must have been at least forty miles distant, 
and in all probability are members of the group of the ‘* Four Peaks” 
mapped on the Admiralty chart as southwest of Eclipse Harbor. Judg- 
ing from their conspicuous position in the sea of mountains, each of 
them must be at least seven thousand five hundred feet high. South 
of Nachvak Bay there are several fine peaks more than six thousand feet 
in altitude. 
The Geology. — Bell has already given us some notes on the nature 
of the rocks in the bay. Additional observations made last summer 
could evidently not form a very complete or systematic piece of work. 
The Torngats, where examined along the long cross-section of the 
bay, are seen to be essentially composed of contorted but generally 
highly inclined crystalline schists, chiefly gneisses. The average strike 
is N. 25° W. At Skynner’s Cove (Plate 12) ledges of common gray 
biotite gneiss and dark-colored hornblende gneiss striking N. 5° W. are 
covered with many large boulders of an arkose-like rock enclosing 
roundish, often large, grains of opalescent quartz. This rock was not 
seen in place ; it may be related to a well-stratified, light colored rock 
series that occurs on the opposite side of the bay. The latter series is 
about five hundred feet in thickness, is manifestly sedimentary and lies 
unconformably upon the gneisses. Unfortunately there was no opportun- 
ity to make a landing and investigate the region closely. It may be that 
the cover represents a continuation of the stratified rocks seen southwest 
and west of Gulch Cape. The rocks of the Nachvak cliffs were sampled 
by Bell, who reported to have found there a slaty breccia apparently 
similar to the arkose of Skynner’s Cove, and, as well, a “ fine-grained 
silicious schist.” ? 
Nine miles west of Skynner’s Cove, on the north side of the bay, the 
well-banded gneisses still strike N. 5° W.; they are here cut by a re- 
markable network of dikes exposed on a sheer fifteen hundred-foot cliff. 
The parallelism of the dikes gave them at first sight the look of sills, 
but closer examination showed that they are independent of the schis- 
tosity of the gneisses. 
Near the Hudson’s Bay Post, the rocks are chiefly coarse, friable
