The Hudson river is deepest at West Point, where also it is narrowest, 
and the bold mountains on either hand give it the character of the Nor- 
wegian fiords. At this point it more nearly approaches the Sogne fiord 
in relative depth than even Hood canal. Both above and below this 
narrow canyon the wider reaches of the river shallow to less than 10 
fathoms (18 meters). The depth appears to be determined by the effects 
of deposition and scouring, and affords no measure of the preglacial 
depth of the canyon. 
The Sogne fiord has soundings of more than 650 fathoms (1,190 me- 
ters), and the mountains on either shore rise precipitously to 2,500 feet 
(760 meters) above the sea. At its entrance the canyon is partially 
filled by a terminal moraine, whose height is indicated by the great 
depths which prevail but a short distance farther in. 
The Norwegian fiords differ from the inlets of Puget sound in being 
features of hard rock topography, modified by drift deposits only on
