Wintery Sunset
#6
I believe it's 6 months and 6 months because of the axis tilt. the sun goes up and down in the summer, but never below the horizon, and vice versa in the winter, anywhere above the Arctic Circle, so I think it happens in Barrow, but not Anchorage. Don't know about Fairbanks though. Same effect south of the Antarctic Circle, with opposite results. I've never been to Alaska, so I'm not 100% sure.

Anchorage never gets the total darkness. Here's from today's paper:
From Alaska.com"
Daylight : 10:10 AM - 3:41 PM
Alaska gets as much daylight and darkness as anywhere else on earth over the course of a year; it's just distributed differently.
Summer is a time of long days. Above the Arctic Circle, the day can be 24 hours long or months long. In Anchorage, almost 400 miles south of the circle, the summer solstice day is 19.5 hours long.
Winter has much shorter days. Above the Arctic Circle, the night can last for months, although lingering twilight brightens the sky. In Anchorage, the shortest day still provides 4.5 hours of daylight.
Around the equinoxes in March and September, Alaska gets the same 12 hours of daylight and 12 hours of darkness the rest of the world does.

I believe, as a general rule, anything north of 66.5° N gets at least one complete day of darkness and one complete day of daylight. The farther north in latitude the more days of complete darkness/sunlight you get.
