Winter Solstice

The shortest day of the year. In Alaska, this is the day when the sun barely rises. In Fairbanks, the sun is up for 3 hours and 42 minutes. In Utqiagvik (Barrow), the sun does not rise at all. The solstice is the turning point. From here, the days get longer. In every culture, the solstice is the same story: the light comes back.
