THE GEOGRAPHICAL REVIEW 
nald Pass. “The broad flat top,” described by Logan as Mt. Mattaouisse 
and separated from Mt. Logan by “a deep ravine,” is the mass rising 
to the south of the Pass; and, just as Logan described it, another ravine, 
The Saddle, “severed it [Mattaouisse] from a dome-shaped top nearly 
its own height [Mt. Collins, as designated by members of our party] about 
a mile and a half to the westward, between which and the gorge of the Chat 
stood another gigantic boss [Mt. Coleman].” 
A party led by Pease made a preliminary ascent of Mt. Logan, discovering 
that its northern and eastern walls plunged abruptly into a basin far more 
rugged and picturesque than Fernald Basin. Further explorations by all 
members of the party, continued over several days of bleak and stormy 
weather by Dodge, Griscom, Pease, and the senior writer accompanied by 
Joseph Fortin, showed that the great gulf which separates Mt. Logan from 
the next dome to the northeast, Mt. Pembroke of some of the older maps, 
was indeed more ragged than Fernald Basin. It was also the home of many 
more localized arctic, cordilleran, and endemic plants; and in recognition of 
Pease’s activity in exploring its cliffs and talus and of his well-known energy 
in exploration of the White Mountains this steep-walled gulf is here called 
“Pease Basin.” To the south and east of the basin extend many square 
miles of meadows (Great Meadows) with numerous small ponds; and, cap¬ 
ping the southeastern crest of the basin are twin summits (Dodge and Gris¬ 
com), separated by a brook which cascades for hundreds of feet down the 
abrupt wall. Between Griscom and the main mass of Pembroke is a steep 
talus of angular gravel, Hanging Valley, with a brook descending its slope; 
but lower down both the brook and the talus give way to a dense scrub 
forest, and opposite Hanging Valley, slightly south of west, is a distinct and 
narrow white ridge of mica schist, Razor Back. 
Some of the party located and tested Logan’s “highest spring of water 
. . . coming from the strata at the upper base of the peak,” thus confirming 
our idea that we were actually following Logan’s tracks; and Dodge and 
Joseph Fortin penetrated the fog, which repeatedly interrupted exploration, 
far enough to see Les Trois Lacs which lie to the east under the dome most 
generally known in the region as Couvert du Chaudron. The latter name 
has been variously applied in the past, but the dome indicated on our map 
is the one visible from Ste. Anne des Monts. 4 Captain Samuel Cote, the 
most experienced woodsman of the region, gave us an explicit account of 
its position with Les Trois Lacs at its southwestern base; and our own guide, 
Thibeault, was familiar with it through trapping in the basin of the Little 
Cap Chat which separates Couvert du Chaudron from Pembroke. In fact, 
Thibeault assured us that the basin which forms the north-facing gulf be¬ 
tween Pembroke and Couvert du Chaudron is much grander than Pease 
Basin. Late in August two members of the party, Smith and Fernald, 
accompanied by Joseph Fortin and Israel Thibeault, reestablished camp in 
1 From the village of Ste. Anne des Monts, Mt. Logan cannot be seen; but its characteristic summit, well 
to the west of Couvert du Chaudron, is visible from the end of the wharf.
