Imagine a land where the sun rises at 1:58 a.m. in the summer and shines for less than four hours on a winter’s day.  The animals in the wilderness near Fairbanks, Alaska, witness some of the world’s greatest temperature extremes and light variations ever year.  At an average low of -16 degrees Fahrenheit, the winters may be unpleasantly frigid, but the light shows are always glorious!
