Ice finally went out of Rabbit Lake in the Chugach Mountains in mid-July, ending fears that a new ice age might be brewing only a few thousand feet above Alaska's largest city. But plenty of snow still clings to the mountains surrounding the lake at about 3,100 feet. And just over a ridge, ice floated in McHugh Lake at an elevation of only 2,900 feet near the end of July...
Most Alaskans expected all that snow to melt away quickly, as it usually does. But it didn't.

That probably won't leave much time between the melt of the last of last winter's snow and the start of next winter. It is not unusual for the higher peaks around the Sound to be covered with "termination dust,'' as the Alaska old timers called early snowfall, by the middle of September. Glaciers, of course, start forming when the snow of a new winter arrives before the snow of an old winter is gone. Snow piles upon snow until the weight of it compresses the snow at the bottom into ice. Then you have an Ice Age.

Endless winter, baby. Endless winter.

Alan Czajkowski, director for maintenance and operations with municipality of Anchorage said bulldozers have been going to different snow pile sites around the city to move the snow around in an effort to help it melt faster. He's doubtful the snow will be gone by the end of summer.
