Walker, a 23 month old polar bear who arrived from Holland's Rhenen Zoo two weeks ago, experiences snow for the first time in his 4-acre enclosure at the Highland Wildlife Park in Kingussie, Scotland Nov 25, 2010. Britain shivered in sub-zero temperatures on Thursday as snow fell unseasonably early, with more wintry weather on the way. Up to 10 centimeters of snow settled in northern Scotland and northeast England overnight, the earliest major snowfall in 17 years. [Photo/Agencies]
