Spotight: Reflecting Winter's Light

A small town in Norway lies in a deep valley, and during the six months of winter, its steep mountains cast a shadow over the town even at midday. From late November to late January, the sun never appears above the horizon in this northern part of the world, and daylight hours are very short. Warm up your research skills to discover how winter rays of sunlight now shine down on Rjukan's town square.
