SOME NOTES -ON THE LAKES AND: VALLEYS "OR 
THE UPPER. "NUGSUAK PENINSULA; “NORTH 
GREENLAND" 
INTRODUCTORY STATEMENT 
Tue Upper Nugsuak peninsula is located in north latitude 
74° 5’—-15'; is 25 to 30 miles long, averaging from four to 
six miles in width, and has a due southwest trend with the general 
coast line of Greenland. This part of the coast is characteristi- 
cally rough and rugged. The marginal strip —at present ice- 
free — is intersected by numerous fjords, which, in many cases, 
penetrate to the very edge of the ice-cap, cutting the uncovered 
land into numerous islands and peninsulas. A considerable part 
of the uncovered lands is occupied by lakes. 
The peninsula is limited on its north and south sides, by fjords 
descending to depths of not less than 300 to 500 fathoms, and 
varies in elevation up to nearly 3000 feet. The hilltops have a 
general elevation of 1000 to 2000 feet. Its surface is a very 
rough and irregular one; is cut up bya network of deeply incised 
valleys, the seaward extension of which add to the ruggedness 
of the coast line. 
The general appearance of the inter-valley areas—hills and 
ridges—is that of a well rounded moutonnée torm, which pre- 
vailingly show among the lower hills a highly polished sur- 
face, while the higher peaks are as uniformly angular, and are 
very much less subdued topographic types. Some of the valley 
slopes are steep, often times precipitous, often with large talus
