The Aleutian Islands and Alaska Peninsula are south of the 

 severe low winter temperatures of interior and northern Alaska,

 low freezing, fresh-water ponds freeze over at times, and snow 

 sometimes piles knee deep. But the snow is likely to be wet 

 and slushy, and there will be some bare ground. At higher 

 elevations, however, snow is heavier, and the higher mountains 

 are snowcapped in winter.
