Just south of the Arctic Circle, Fairbanks is a popular tourist destination. People even visit in the winter just to see the aurora borealis. Also called Northern Lights, aurora borealis are brilliant colored lights that dance across the night sky. In Fairbanks, people can be seen mining for gold, dog mushing, performing traditional native dances, or floating down the Chena River on an old-fashioned riverboat. (ALAMY)
