One of the things that Alaska has that most people in the rest of the United States doesn't have is ice fog. That's when it is so cold that the moisture condenses out of the sky and rains down on us. It clings to everything, and it's known as hoarfrost.
The world is white with ice crystal and snow until the wind blows it all away.
This is from my front deck, with the camera sitting on the railing. It's about zero degrees F., and the time is around 6 pm.
Our winter days are very long, with Anchorage getting about 5 hours of daylight on Dec. 21st. Then we start gaining light until we have summer again and long days.
