It will be seen from the map that the width of the bay averages about 
one and a half miles. Its length is twenty-five miles when measured to 
the head of either of the two arms, the Tallek, or the Tessyuyak. Weiz’s 
map exaggerates both dimensions considerably. It is important to note 
that the trench filled with the salt water of the bay is continued at 
the head of each arm by a wide and deep glaciated valley. That cor- 
responding to the Tallek runs to the south, its floor rising slowly, until, 
at a distance of about twenty miles from the Bay, it terminates in a flat 
divide adjacent to the valleys drained into Nullatatok and Saeglek Bays. 
The upper end of the Tessyuyak has been dammed across by a splendid 
alluvial fan that is growing vigorously out from the mouth of a hanging 
valley, the floor of which stands about one hundred feet above sealevel 
on the south wall of the inlet. The result has been the formation of a 
fresh-water lake, the Tessersoak, three miles long, which is drained by 
a rapid stream slightly trenching the fan. Beyond the lake to the 
westward, the deep valley extends with but little abated strength as far 
as the eye can follow it when viewed from the top of the fan. Mr. 
Ford informed us that the valley leads directly across the Torngats to 
the flat country on the west. The total length of this whole valley is 
thus about forty-five miles; rather more than half its floor lies beneath 
the sea. 
On both sides the bay is walled in by very precipitous cliffs varying 
in height but averaging nearly two thousand feet above the sealevel. 
The highest point immediately overlooking the water is unquestion- 
ably the summit of the Idyutak, where its western face dominates the 
Tallek (Plates 3 and 4). Its height (3400 feet, bar.) was long since 
Kipsimarvik, meaning unknown; old Eskimo word perhaps, of which the mean- 
ing is lost, as in the case of many names of places. 
Kogarsuk, “ small brook.” 
Korlortodluk, “ big water-fall.” 
Kutyautak, “ wedge,” referring to the shape of the mountain. 
Nuchvak, “found, found at last.” The first Eskimo, coming from the west in 
search of the salt water, cried out “‘Nachvak ” when he reached the head of the 
bay. 
Naksdluk, “ great valley.” 
Sennerkitte, “tributary, branch stream.” 
Sittorutsit, “mountain side where avalanches are common.” 
Tallek, “arm,” referring to the shape of the bay. 
Tessersoak (also Tesseksoak), “large pond.” 
Tessyuyak, “like a pond.” 
Tinutyarvik, a basin at the head of a cove, barred off by a continuous wall-like 
shoal, so that at low tide fish are trapped as in a weir.
