tance of the width of the 
Narrows, to lie at the 
575-foot contour. No op- 
portunity presented itself 
for the ascent of this 
southern ridge; hence the 
line at St. John’s could not 
be placed more accurately. 
The observations at the 
Hudson’s Bay Post in 
Nachvak Bay gave as in- 
disputable evidence of the 
relatively low position of 
the highest shore-line as 
was obtained at the other 
coast stations. The po- 
sition of the boulder-limit 
and the entire absence of 
elevated beaches at heights 
greater than 250 feet mean 
that that elevation is very 
close to the level of greatest 
postglacial submergence. 
If the record of the 
table be put in graphic form 
(Figure 4) it becomes still 
more evident that along 
the eleven hundred miles 
of coast the elevation has 
been differential. The pro- 
nounced warping of the 
highest shore line is incom- 
patible with the view that 
changes in the position of 
the level of the sea over 
great stretches of the 
earth’s surface, are pro- 
duced solely by independ- 
ent vertical movements of 
the surface of the ocean.
